It is fully playable on mobile, but the buttons don't click very well so I would not recommend it at all. There are a total of 40 levels, where the first 10 are just platforming levels, the next 10 have spikes, the next 10 add saws, and the final 10 have a second layer of spikes that move on an opposite timer. Technically though there are a lot of levels because every one is procedurally generated, and random each time. Thank you for playing my game, I hope you enjoyed it!
