Thanks a bunch!
For the jam I really neglected a lot of basic features (like any kinda options menu) but I'd like to sort out proper control re-mapping/controller support for a full game if I continue working on this.
Quite a few features I'd actually like to include in a more full-fledged game, such as optional upgrades/loadouts, refined mechanics overall, and probably a lot more. Definitely could do Linux as I did that in the past. I'm unsure about Mac exports since I don't own any Mac devices, but would definitely want to look into that also.
Thanks again!
