After all, I still know how to do optimized 3d games.
This game (temporary project name - Area#7) is oriented on mouse aiming (when you click anywhere, character will attempt to move in that direction), timing, and puzzle solving.
The water-blue thing in screenshots is ice. When stepping on it, character will slide, and you can turn him around (that means changing sliding direction too) by clicking anywhere.
The cyan-blue thing (like in first screenshot) is crystal. It provides much higher sliding speed, and no turning possibilities.
Green sphere things kill you easily, as well as falling down into darkness.
When you die, you return to last checkpoint (or start-point if you didnt got to any checkpoints)
As well as checkpoints & exit points, some levels include secret places (normally not so secret, the main challenge is to get to them alive), which increase your
