It wasn't very clear what the objective of the game was. I guessing I was suppose to collect the objects on the board, but there were times were I was sure I collected all of them and the game continued, while other times I only collected a couple and was told I won, and at least once I was told I won without collecting anything. I think what might be happening is it doesn't fully reset between games, so if I get hit by the enemy with only a few left to collect, and then collect them on the next round I get the "you win" screen, even if I didn't collect everything that round.
The screen size is rather small, which made playing difficult. The collisions also seemed a little off, as sometimes I got caught on a wall or corner when it looked like I should be able to keep moving. This may have just been due to the size of the screen, and missing a bit of the wall, but it wasn't very clear, which made the game a bit frustrating.
