I really liked this game. I think it could greatly benefit with a few tweaks. For starters I would have the jump button be both space and W (unless w is used else where). Having W be the jump button would make hasten the pace of the game which I feel would benefit it. I would also add an indicator as to where your attack is going to hit (specifically switches) as it tells the player they can actually interact with the environment.
Also I think the game is a little broken as I got to an elevator part where the platform would not rise far enough for me to continue progressing. Overall great core (truly) just needs some tweaks.

Are you talking about the elevator part in level two? If so, you are supposed to wall jump on the wall (which if you didn't know we had a wall jump it's the thing you collect on the first level, I will make an update soon with text since we never tell players there is a walljump). Also, W is to aim upwards. We are going to release some updates soon for the game like a balance one and a juice one so hopefully that addresses some of the issues you see in out game.
