This maze-like platform game lacks extra polish in its controls: jumping feels off and shooting is totally inaccurate. I have never figured out why some ennemies are vulnerable to my projectiles and some are not. The music is a wonderful classical piece, the moonlight sonata, but sadly it is repeated ad nauseam. Fortunately, it can be turned off, a proof that developers were conscious about the issue. This giant collect-a-thon is definitely not my cup of tea.
