Subtera Puzlo by EgoTrip is a homebrew puzzle game for the Nintendo DS console. The object of the game is to escape each screen, collecting the coins, and the key that will unlock the exit. There is an initial time limit of 30 seconds. Avoid the guardians and traps, colliding with these will result in a failure.
