Thanks so much :) Like y’all, this was my first real Godot project and messed some things up. SML.E’s rigidbody wasn’t properly looking for the suit’s collision so it wasn’t properly being affected by the jetpack. Eventually with the gun the reason SML-E has a hitbox makes more sense, but as you correctly figured out the laser gates at the end I think are impossible :( The ui in the top right is also ammo for your gun and will, eventually, power a rechargeable shield for SML.E
Here’s a lil vid of what it could (or should) have looked like, had I fixed those two things… still ends with a bug with the save console, but shows off a little of what gameplay can be like with the gun!
