UpBot Goes Up

The premise of UpBot Goes Up is simple: the player needs to guide blocks of up to four colours into the positions of the corresponding colour. The problem is that each block can only move in one direction (e.g. the yellow blocks move up and the blue ones left) and all blocks of the same colour (if more than one is present in the puzzle in question) move simultaneously. Of course the levels can't be just solved by moving the blocks forward; they need to move each other around, e.g. to move a non-yellow block upwards, it needs to be put in front of a yellow block first. Many levels also feature teleport stations. Because of the nature of the game (the player needs to figure out the correct order of moves), it is easy to create an unwinnable situation. To prevent this, the player can undo all moves one by one until the initial situation is restored. The game features 60 puzzles of increasing difficulty.
