Overall I really liked this game. Props for thinking outside the box with “bloom”. I think the essence and ambiance of space was captured well. The music was very fitting too.
The controls felt pretty good - kind of like a twin stick shooter. Shooting was a bit repetitive before I realized I could upgrade my shot strength. Upgrades should probably pause the game or something when opening. It was also not apparent at first how to upgrade things other than energy, UI wise. That said, the upgrades in normal mode felt impactful and scaled well.
Physics wise, my main complaint was that the point where gravity started was very apparent and jarring. I would consider making the range as wide as possible, and letting it get exponentially weaker with distance. I believe Godot’s point gravity system has this ability built in. The space friction was also a little disappointing, because I was hoping to slingshot my rocks :)
UI wise, menus could be cleaned up, and a star indicator would be helpful. Surprisingly I lost it a lot, particularly in hard mode when I was really trying to scramble.
All in all this was a really great submission. I played it a few times. Nice work!
