The game was extremely laagy when I first tried playing it in full screen mode, but it works great with the regular window size. Just wanted to point it out if anyone else is struggling with the same issue :)
The game looks really good! And it feels great to play, you really nailed the platforming mechanics and the animations etc. It was a bit confusing with some enemies not really being killable, and I found some other ones that got a little bugged (it escaped the map in a room so I wasnt able to kill it and got stuck in its room).
Really great job with the game overall!!! :D
