This one nice platformer game. The movement of the character is really well made.
There is one area where the player can trap themselves if they are holding the box. I sometimes find it hard to notice the enemy because their sprite texture blend in with the background. And there are similar floor sprite which they look the same and not all of them are solid making me mistakenly standing on the non-solid platform and fall to death.
The game looks really nice by the way. Nicely done.
