Really nice little game. I think your art was really well-done and looked nice and crisp. I liked how you implemented different kinds of attacks too, I came across the right-click attack by mistake but it looked really cool!

One thing I might like to see adjusted are the collision boxes on the shelves so either you could jump through to higher shelves or at least have a narrower box so you don't clip as hard when jumping off of a shelf. If you plan to continue any work on this, I think it would also be good to maybe add a score system too, just for bragging rights and whatnot. Like I said, it looks really visually polished, and with some work on the gameplay, it could definitely turn into something really neat! Great job.

It looks like your fonts are alias/hinted, which means they aren't just white - they're white and a bunch of greys. Regardless the game is pretty, albeit hard! I'm not sure I understand how much my batteries charge from defeating an enemy or getting a chip. Regardless, good work!

Your project seems really cool, but I can't launch it on windows, I get this error 

I don't know anything about godot so I can't help you, sorry :/
