Trigono is a game of survival with rogue-like elements.
It's the love child of a threesome between super-hot, asteroids and Binding of Isaac.. and Particle Mace maybe.
You play as a triangular ship, and a little friend will follow you and shield you from enemies. He also gives you the power to slow down time when you don't move.
But if you are hit by an enemy you lose contact with him and you'll have to try to regain contact with him, without any of his time manipulation powers and with a black mist that begins to eat the space around you.
If you can't rejoin with your fellow adventurer in time you are dead.
