Toodee and Topdee (559 reviews)

Puzzle platformer/block pushing hybrid

The 2d platforming world and top-down world have smashed together. You control one hero from each dimension, who share the same space in the levels. You switch between platformer and top-down modes and must get both characters to the goal. The boss levels are hard but very cool, combining action and puzzles.

Also features local 2-player co-op and a generous assist mode.
