Wow that was surprisingly addicting, my economy started to ramp up really fast once I got that third flower into my farm and it was fun to see how fast I started killing enemies once I got that going! One small thing I noticed (and I'm not sure if this was intentional or not) but the bullets I fired seemed to move with my character as I moved around instead of keeping their own trajectory in space.
Excited to see where you go with this if you continue to work on it!
