Hola guys, thanks for your kind words.
grandbrinus I can see your point, and the idea is for the full game to let you earn some level credits. I'm not gonna work with checkpoints, but what I want to achieve is that once you finish a level, you get a credit for this level. Like when you start a new game, you won't start at the beginning, but will start at the last fully finished level. I think this is a good balance with keeping the difficulty up, the frustration a bit down and not making it a walk in the park
Anyway, thanks for your review.
Funny about Meat Boy, didn't even considered him...this game I based on a very old Atari ST game where you are a bubble in a maze.
