I tried to think of a way to make a game about a minimalist lifestyle, or at least the pursuit of one. And so, here is a Metroid game, of sorts, where instead of acquiring powerups, you must get rid of them. All of them. Though the order in which you do so is up to you, certain areas will require certain power ups to access. Planning is key! If you place a power up you didn't mean to, you can pick it back up after a second or so. It is, unfortunately, possible to get trapped if you don't plan appropriately, just delete the data.dat file if you have to start over.

Controls:
arrow keys: move around
up: save/use lift
down: use lift/duck/turn into ball

A: jump (double jump if you have the Screw Attack)
S: shoot (hold to charge, if you have the Charge Beam)
D: select missile or super missile (if you have them)
Space: Pause/View current power ups
Escape: Quit

Some notes on things that you might expect to work that don't:
The screw attack doesn't work as an attack, it can just break down certain walls and get you to high locations

The ice beam will freeze enemies, but I didn't have time to make them work as platforms, so it's only really useful for metroids.

The power bomb is used by charging a shot while in morph ball mode, rather than selecting the power bomb using D

Oh, and no shinesparks :(
