It's a good game. The art is good, I like the music, the sound effects and the concept too. The chest is kinda slow so you have to spam the arrow key. I found some "bugs": 1. The hero will go back to the green button to open the green blocks even though he doesn't need to go through them anymore sometimes. It was especially noticable in a level but I forgot which D:. 2. You can walk through the hero without him opening you if you spam the arrow key fast enough. Other than those I liked the game.
