I just tried playing with "Bad" graphics and it definitely felt a lot better, with a framerate which I'm still not sure about but which definitely reached 60 fps or higher! The inertia was also gone.
I didn't play to completion but noticed a couple things I didn't notice before:
- The left and right screen borders are not sized the same, the left one takes more space while the right one takes less
- When trying to move diagonally into the bottom screen border, the ship slides. Maybe it's part of the reason I thought there's inertia
- When going into focus/small mode, you can no longer move diagonally
As for the last bit - there is still a lot left to learn so I don't think I'd make a good teacher, but I'm open to share thoughts and stuff ^^ Handle is @wingedfoxdev, I'm on the bigmode server but didn't message much yet, maybe we can chat there!
