This hack is for lighthearted fun and silliness. It's built around the gimmick of making sure Samus is always in the bluesuit state.

In vanilla Super Metroid, "bluesuit" is the name of a glitch that gives you a stored shinespark that you can use later (similar to the well-known "spikesuit" glitch). However, when you have a bluesuit, there is no need to move carefully because you still need to crouch before a shinespark can be activated. In addition, while you have a bluesuit you can move through most enemies dealing massive damage to them, similar to screw attack.

In the easy version of this hack, shinespark health drain is disabled, and the crash animation is shortened to 10 frames, so there's basically no downside to intentionally shinesparking everywhere to get around faster. Normally, invincibility frames are disabled when you have a bluesuit. I've tried to provide vanilla iframe behavior, but it doesn't work in all cases. For example, watch out for Ceres Ridley's tail. However, bumping into his body should provide normal iframes. Landing on spikes should usually give vanilla iframe behavior, but in a few cases it may still behave as though iframes are disabled.

The "normal" mode re-enables health drain, the full crash animation, and no attempt to improve iframes is made.

Special thank you to Ob for helping me by giving me the code for ensuring Samus always has a bluesuit. Thank you to Kyzentun for the idea. Thank you to UNHchabo, as I've based this patch on his wonderful Eternal Spikesuit. And thank you to my play testers (squidman and jooniejoone).
