First off, not a game dev!
A fun little clone of games like Thomas Was Alone, without the narration, of course. It's fun, but when I got to the room with the "B" and "S" blocks, I couldn't figure out how to get the key. Outside of that, this looks good.
EDIT: Hahaha! Just saw in a GIF on this page how to get past it. I'll hafta remember that.
