Enjoyed this quite a lot! The platforming feels smooth - particularly like the dash effect. I was wandering around a little before going down the platforming pits after getting primed by your death pit (I usually try to avoid subverting player expectations like that) and went to the right pit first, where the platforming ended up having a huge spike in difficulty, so that difficulty curve probaby could have been smoothed out a little bit with some extra checkpoints. (WASD did not work for me by the way, only arrow keys). Overall really enjoyed it, this game has a great vibe and feels great to play!
