A really nice platforming game! It's very hardcore and there's no life system or checkpoints, so if you aren't a pro at platformers, it's gonna be tough to get to the end. I haven't reached the end of the game yet but maybe some sort of checkpoint or life system could be added?

For example, for the life system, maybe you can get three lives and each time you lose a life, you respawn to a previous section but not all the way at the beginning. If you lose all three lives, then you start over. Just an idea but I think people would like something like that! :)
