I think that the idea of this game is amazing, but it is very annoying. The first few levels are ok, but the later levels are annoying: there’s a spike, so you jump. And then you hit a spike on the ceiling. Also, half the time the ball doesn’t jump when you tap. There are also WAY to many ads, most of them being videos that happen almost every three deaths. Oh, and by the way, NOBODY will cough up 2 dollars to remove ads on a cheap grab for money that you’re just going to delete within the next hour anyways. I’m sick of dying the second I start the level. Also, when you beat level 50, it takes you to a black space. Skip that level, and it puts you in level 21.
In short, this is a glitchy, low quality, cheap grab for cash. The levels get too hard too fast, mind you that there are only 50. There are also only three controls: tap to jump, do nothing or tap to die, and do anything or nothing to play an ad.
To improve this I would recommend less ads, more levels, less spikes that you die on mid-jump, and more features, like endless mode.
