I played this for 10 minutes , this is pretty cool as your first finished game, it's a nice concept too, could have some other gamemodes (Like vs. multiplayer) but it's fine like this.
Hey. I played it on Linux. I had a minor problem which I seem to have with all unity game I've tried on itch. The issue is that the shapes do not render properly and kind of appearing just like textures. The fix was to run the game with the flag:
-force-vulkan
It ran great with that so it seems to be an opengl issue.
