I just played the game with my daughter and her verdict was: tough, but cool! I can’t say anything against it. Compared to the hundreds of other jump and run with dead body games, yours is truly refreshing and different. We had a lot of fun checking out what the different plants do.
I think, however, that the control mechanic can be improved. The jump was quite unresponsive and the movement very sensitive and fast, which made it hard to navigate precisely.
