Hi, this is the same person as before. Why after making the jump, when you try to go through the doorwayish thing you die?
A few more things. Are the graphics fixable? It kinda messes with me. Could you make it so you can hold shift and jump at the same time? that complicates the game a bit. lastly, is there a reason for the key in level 1? Also, could I get your email address? It would make this a lot easier, and probably better for you too so potential errors aren't publicly pointed out.
