ok, based on the controls alone:
W does not work to enter the door.
In the instructions menu, J is listed as the jump button.
Also, invicibility does not work. I got killed by a beetle when i was invincible. Not possible. Invincible means you are impervious to damage. not that you can get killed by beetles.
Also, you can move while chargeing invicibility. Charge then hold down a move key and you will move.
Untill these are fixed, im not playing anything past the first level.
