Today I learned the hard way how difficult it can be to keep spaces and tabs separate. After adding in a font character to my TIC-80 config (so I can see the tabs) everything became much clearer.
Progress for today was limited to limiting (the amount of "bullets" the player can have on screen at once). I set it up to be an upgrade-able variable - in the event I actually keep working on this, and also worked out some kinks that I added from trying to add different types of bullets.
