Hey 3koozy!
Awesome that you use godot too, I love it!
As for 1: Yeah my plan was to do powerups AND achievements but I realized that was out of scope for the jame time unfortunately :(. But powerups are collectables right? lol
As for 2: yeah I spent quite a while trying to fix this but couldn't quite get it right, but I also realized that if you hold both the forward and either side buttons you get a smooth orbital movement and so I thought it might actually be nice to have a lil centripetal force pulling you outwards. Once you know to expect it, it becomes an asset and lets you evade enemies, but then I found myself using the actual back button much less often. idk, definitely something I would like to work on, but vector math hurts my brain!
