Bugs
The are some, bugs set in the game but not noticeable till you play, so you can possibly get away with it.
Strengths
The game was fun jump mechanics are some of the best. This game is also visualising appealing
Weaknesses
Other than the bugs not much. don't know what the darks hearts are for so might need to explain that.
