One of the most challenging platform-adventure games with a random generation system is Prisonela. It means that a fresh challenge will be waiting for you on every level you play, even if you perish in one type of stage.
Avoid tripping over falling spikes, traps that move left and right, some of which are sitting on the ground, and some of which are even installed on the ceilings.
It might sound strange, but to get across the flaming pit at the conclusion of a level, you'll need time, bravery, and ability in order to keep going.
How to play
The up arrow key is used to leap, and if you hit it again while in the air, you may perform a double jump, which you will need to do quite a bit.
