Show HN: Angularis – like Tetris, but based on triangles (angularis.mondaybits.com)

106 points by rufname ↗ HN
Angularis is a game similar to Tetris, but based on triangles instead of squares. Which is why it also has diagonal movements. I had this idea about a month ago and built the game in my spare time.

I think it is a bit more difficult compared to Tetris. You kind of have to get used to "think diagonally".

Maybe it can be a nice little challenge for you.

I'd be happy to receive some feedback. Thanks!

My brain really wants/expects 45 degree rotation. Not saying you should add that though, it might make the game too easy.

edit: and playing some more I see 45 degrees wouldn't even really work.

Oh man, this hurts my brain! I still haven't managed to clear a row, but I'm trying!

Just a small quality of life request: could you add a little more delay when the block touches the bottom? I feel like when I try to fast drop the block it finishes dropping a little too quickly and I can't slot it into place easily without gently tapping the down arrow to adjust the speed.

Fun, but definitely hard! Love that fact it has touch friendly controls, of note though, I needed to two finger tap to rotate which wasn't clear to me from the help text!
Cool game! Super simple and I like the added challenge.
Feels a bit too hard, I've only managed to clear one line. Building straight lines out of triangles seems hard, there are so many overhang pieces. Not saying it needs to be easier but I might need some help to get started.
If the pieces could be rotated by 45° that would help I think?
It needs a 2-piece triangle to make a lot more empty spaces viable, or even an occasional 1-piece to allow for fixing mistakes
Uff.. I'm struggling over here. This feels like knots in my brain. Fun!
Because it's so different, and takes some time to get used to the different ways that you can move pieces and slot them together, I think that it would be helpful if there were a practice mode that disabled the auto-falling, to remove the time pressure element.
Couldnt clear one row but am loving it!!
In my browser (Firefox on macOS), the buttons to the left of the game (pause, music, etc) don't work when I click on them directly--it just makes pieces rotate. It seems that I have to click just to their left in order to use them.
Like the idea. Can’t get even one row to complete after playing for far too long.
Nice concept but there’s a few areas this can be refined to keep the difficulty the same while making the game much more charitable to players.

1. Given you have triangular blocks and diagonal movements, the board should probably be angled too instead of rectangular. Maybe experiment with having a tapered bottom to the screen.

2. In Tetris ever piece can connect with every other piece to form a new block. This isn’t true here. You have some blocks that are squares (orientated with a flat bottom). Some that are squares by diamond orientated (ie rotates 45 degrees). Some that are entirely diagonal. This means that a lot of the pieces do not work together. You’re also effectively creating 8 different orientations to match rather than 4 while still only allowing shapes to rotate in 4 different orientations. So you need to spend a lot more time deciding upon what pieces are available. I don’t think having more pieces is the solution here either because you just reduce the likelihood of a piece you need from dropping.

The controls work surprisingly well on mobile though the drop button is a little too Easy to accidentally hit. But that’s nit picking because it’s a pretty decent experience otherwise.

It would be cool if you rendered the (triangular) grid, and showed a drop preview. In its current state, I never have enough confidence to hard drop.
yeah that would be a cool feature to start understanding this new shapes
controls unintuitive
Very cool, very hard. In fact I'm wondering if the shapes (when randomly chosen?) don't make it impossible for the player to keep the game going indefinitely (as you clearly can in Tetris). I wish I had the proof chops to examine this claim.

(I only managed to clear one row.)

The worst state in Tetris is the endless stream of "zig zag" shapes, but at least with those you can alternately sacrifice and clear rows, usually.

With this, I am not convinced that the pieces are allocated in a way that remains playable. I have cleared a couple of rows (in different games!) but there just seems too much stacked against me for progress.

It could be due to my eyesight; the board area needs visual hints. It could also be due to the controls, which seem like deliberate hardship.

It is cool, but it's too difficult to be fun; there's almost no recovery possible from accidents and there are too many ways to have accidents.

Fantastic! You should be very proud.

Took a while to get used to it, but I was very satisfied to clear a few lines.

I was curious what effect it would have to change or add to the concept of "row" to be not horizontal, but instead a "strip of contiguous triangles from the bottom to one of the sides." I might also try instead of a flat bottom, one shaped like an inverted triangle.

Very fun, but could use some polish. Controls need improvement. A single key for rotating would work better (arrow up is the most intuitive and indeed I keep hitting it and accidentally "storing" a piece for later, which is a great concept but should be bound to a different key since the arrow keys convey movement). Should show instructions in the same page as the actual game. In fact, the home page should be the game, with the other stuff tucked away (see e.g. the Wordle page for one potential UI/UX approach). Graphics could use some polish, typography / CSS too
The up arrow to store was the biggest problem for me. I ended up doing this about 10 times in about 40 pieces, just because it's muscle memory from Tetris.
Same here. Also, such games would certainly benefit from single-hand operation in mind. I'd prefer UP for rotation, DOWN for drop, and, maybe, PgUP/DN for L/R rotation, END for hold. And similarly on the WASD side of the keyboard, so either hand may be used optionally. Or even for one-keyboard multiplayer. )

I love it and hate it at the same time, I couldn't clear a single line :) Those green blocks are evil.

I like your sound design choices to use drum machine samples.

I played it a little bit and I felt like murdering someone ;) Simple reason. I am very decent Tetris player as to me it is a form of meditation. And hot key to rotate that shape is hardwired by now. So to me this has completely spoiled what could be a decent game.
Fun game. Cleared two lines! Green blocks are evil indeed.

An annoying thing is that the apparent buttons on the left don't work since a mouse click rotates the block instead. I needed to mute the browser tab because I couldn't click on the sound button.

Nice idea! Only two annoyances are the vertical scroll that up-down keys mess with and that the up key doesn't the thing like it does on normal tetris.
Nice, looking forward to the NYT acquisition.
Surely "Tritris," by analogy with "Tetris."

Actually that was the original name I had in mind. But I found it to hard to pronounce.
