Press space and arrow keys for movement, collect the key and go to the door to test out collisions and unlocking areas, and walk off stage in either direction to test out moving from scene to scene! Didn't test out platforms, sadly. But I will say that I've completely revamped my code for movement in this short amount of time, so now I can have smooth movement! Next up will be hopefully getting some helpers to sign-up...
@-Mr-Plasma- for some of the code.
