Not a huge fan of plataformers and getting stuck on the second for as long time almost had me quit but i hmade it to the end. End credits box explosion was a cool reward at hte end of the tunnel.
Sfx is nicely placed and alooks the par for my expectatioms for this type of game. Whenever the levels didn't frustrate me it was enjoyable. And i did stick to the end till I cleared it.
EDIT: forgot to say, the checkpoint design is great.
