Perplatual

You are stranded on an alien planet teeming with enemies, hazards, and complex terrain. Fight and navigate your way through level after level to find your way out. (Spoiler: there is no way out.)

Perplatual is a procedurally generated "endless" platformer with a near-infinite amount of possible levels. The project was developed as a self-training exercise, thus it may lack some features and polish you might expect from a commercial game. It will run in Windows in fullscreen or windowed (1600x900) modes.

Each level is comprised of 4 to 7 "rooms" that are blocked off from one another. You must locate each colored key and its associated lock, proceed through each room, and finally reach the exit to start a new level. There are 15 types of alien enemies with varying degrees of health, speed, and difficulty, 5 parallax backgrounds, powerups, coins, and environmental hazards.

Levels are generated with a custom algorithm that corresponds to the player's movement, speed, and jump height. Admittedly, as I cannot test every possible iteration, some levels may be unsolvable, though this should be extremely rare. If you find an unsolvable level, locate the 6-digit seed number in the upper right and let me know in the comments.
