Well done!
Great effect when reavealing the true. Art and music are good.
I only wish that spacebar was used for jump. A few times I tried to jump with spacebar but ended up revealing the true instead. Maybe that just happens to me (my game is also a lot about jumping with SPACE so...).
I felt it was a bit difficult at some points. If you keep working on it maybe consider making a longer game with easier levels at first.
Congrats!
