You have to reconnect with your triangle brother to progress levels and to see the end. Use WASD or arrow keys to move! Collect a coin or not, and try not to die. Use the power of momentum to beat levels. Hold up to wall jump. (This is a decently hard game do not play if you get frustrated easily. But, leave a like and favorite if you're here already. :D)
From a gravity test to now a parkour platformer it has come a long way. Some Art by @__-Champion-__ There is different triangle art in the costumes :p.
