It's a fun little game. Gunning down the robot hoarde and running around is satisfying. But I feel like there needed to be more visual/audio effects, especially whenever enemies are hit.
I liked exploring the dungeon too. One of the rooms had a shark aquarium I believe.
I'm a bit divided on the "Low Power" downgrade mechanic. There are some things I like about it, and some things I don't. On the one hand it gives the game a strategic element, where you have to prioritize some abilities over others. On the other hand, I feel that the downgrade screen appears too frequently, and that it nerfs some abilities too much: sprinting can become slower than walking, and jumping can become as effective as standing in place.
Finally, I'd like to give you props for building a 3d game with GoDot. Mad respect for that.
