Nice little game, it was quite nice to be able to play. The invisible trap make me think about this Mario game, way back in early 2010, where the game was trying to kill you constently.
I think the controls add some jankyness when playing on the keyboard, and it would probably have been better with a gamepad.
I also had some problems to enter the door to go through each level, didn't quite catch that.
Either way, really nice and funny game, keep the good work !
