well done! have you checked the instruction manual already? I've learnt of 1 technique when play testing where you press almost every button that you can input at once to phase through the wall on level 2. One thing I forgot to put in the manual is that pressing u resets the game so you can try again without reopening the exe :D
Game talk aside (I need to contain how much I've learnt about this silly little game jam game I made) I'm glad you like it. I'm surprised I was able to make a versatile enough game mechanic to bring a hint of replayability to this which I'm very happy about. Thanks for the comment too!
