Wow, that really hurt my brain! This was so much fun (and frustrating, but that's probably not surprising). I don't have any critiques, other than maybe slow down the movement as sometimes I accidentally go in a direction too many times. I made it all the way to level 15, but gave up there, that level feels almost impossible. Our game is actually very similar to this one, plz check it out :)

Thank you so much! Me and @viv29 we're actually in disagreement over the movement speed, I wanted to have it faster and he wanted it slower. I guess I have the unpopular opinion! We will definitely tweak that. An idea I had would be to have the movement be very snappy, but have a delay between moves when holding down the key, I wonder what you think about that? About level 15, we thought it might be a little too hard, so we've already made changes to it for after the jam! It's really cool that your game is so similar to ours! I would play it, but I'm only playing browser games, sorry! Looking at the screenshots, the art looks very nice.
