Arrows to move Z to jump (Hold to jump higher!) X to attack C (Hold) to run V (Hold) to see energy percentage S (Hold) to equip missiles (Once unlocked) Minimap is not 100% accurate. Sorry for the bad graphics and only-green coloring, but this is based off one of the older Metroid games. Fullscreen is recommended for the best experience. CREDIT: Give credit if used. The sounds and real-looking sprites are from @SuperMetroidSamus , The collision style is by @griffpatch , but everything else is by me. Credit to all people mentioned above. UPGRADES (In the order you get them): Hi-jump boots: Increases your jump height Missiles: Unlocks Missiles, which can open bright doors Spazer beam: Triples your beam shots. Does not apply to missiles. Varia Suit: Changes your color and half's damage from enemies. Energy tank: Increases energy by 100, drastically increasing resistance to enemies. Also gives heat resistance.
