Decent game. I've played one other game like this before and the biggest limitation on that end was that you had to go so fast or the game would kill you, which made some parts literally impossible due to rng. On the end of fairness, I give you props, however, there does seem to be a miscommunication as far as the character's hitbox goes, which is to say that the player can actually go through some spikes, lasers, sawblades, etc. While the lenience is nice for allowing progression through otherwise impossible areas, it's disadvantageous to those who might not notice it and know to take advantage of it. As far as rewards are concerned, they are priced a bit too high for what little content this game offers aside from its difficulty but perhaps I'm mistaken as it seems to be meant as a mobile game; something you can pull out of your pocket to kill time. So, for a flash game on computer: eh but for a game on mobile: kudos.
All in all, the game is slightly better than average
