Triple Take is a series of unexpected experiences in the form of a fast 2D precision platformer where the level evolves as you complete it! Run, wall jump, climb and swim through increasingly difficult levels in (un)vibrantly colored worlds!
When you start any level for the first time, it might seem to be almost too easy to beat, but the levels evolve when you play further. Every time you beat any level, the level changes somehow and you need to play it again. Three times. Triple Take. Ok, you got it. This makes completing levels… difficult. Jumps become more difficult, new threats reveal themselves, and new pathways open up! Difficult.
