Pretty solid game, this is the first release of Brazilian JoyMasher, and they started with an awesome game, its difficult is balanced in a way you are able to get better on every failure, there are no checkpoints so you have to re-start from the beginning of each level, but there is no game over on standard mode, and levels aren't that long, so I found it fair enough.
Had some little problems with control responses sometimes that annoyed me a little bit, and that damn knockback, geez! Music team did also a pretty good job here and the graphics took me back to the NES era entirely. Overall, pretty good game and a great first entry by the team.
