Thank you for your feedback!
Yeah, I need to rework the burst of mini bolts. It’s meant to help you escape tricky situations at close range. However, as it stands it’s difficult to see because the mini-bolt appears in the trail of the main bolt. Levels 2 and 3 of the upgrade give you more mini bolts, but since the game only has 7 stages for now it’s rare to be able to get the upgrade to that level.
This is what a fully decked-out mini-bolt gun looks like 
I’ll definitely keep your feedback in mind if I flesh out the game after the jam :)
