Boop. Interesting adjustments to the overworld, did a few runs and the energy drain's working nice, same with shield chips and basic shield. Encountered a few other bugs though:
-If you have >10 shields, and you activate your basic shield, it resets the shields back down to 10 (intended or not?).
-Shield chips have no effect on Shield Drones, despite them apparently being compatible.
-If you go to the options menu (nice btw), and hit quit, it doesn't actually quit. If you press play again, it takes you right back where you left off and doesn't reset the game state.
-If you go to the options menu and press continue, the mouse click carries through as an action in the play area (IE: clicking continue and it simultaneously mines a rock under your mouse position as a result).
