Great work! Absolutely love the artstyle. It turned out really well :D One thing that I found missing was some sort of direction aid like a map or something more ingrained in the levels, but because rooms are often so large with multiple routes it felt like I'm missing out on something if I just go a certain way. This made me (which might be of interest to the game/level designers) alter my playstyle, switching from calculated jumps and grapples to just spamming it in a direction hoping I run into a wall or ground and not something that would kill me (which in turn made the game feel unpredictable and in-turn frustrating in a way after a certain amount of time?)
That being said, again I enjoyed it overall, and amazing job with the art :D
