Beautiful game! Levels are challenging and sometimes even addictive.
I love how the menus and the UI are integrated within the game. The close button is a nice touch for rage quitting lol. Overall it feels very minimalistic.
I found a visual bug at level 13 in the level counter, I'm adding a video showing it.
The video is very slowed because the software that I use to record the screen slows it a little, and also because the laptop where I've been playing it (with wine) runs it a little slower than normal. I played it with an older computer and surprisingly it runs faster, but it also has that bug at the 13th level, so I guess that wine isn't making the visual bug.
