These types of games have been around for a long time and I still enjoyed trying it out and testing my way through the game.
The reaction time of the platform could have been faster, because even when the rabbit (for me it was a rabbit! :D ) was in the air and you clicked, it often missed because the reaction time was too slow. I found that a bit of a downer, as it took away from my enjoyment of the game after a few minutes.
Still, it was a good, solid game. I liked the concept of collecting coins and the effects of hitting the blocks were surprising and new.
You really got something good out of the gamejam! Well done :)
