Thanks for playing and the feedback!
- boomstick and super boomstick, their bullets could do with some speed variation. currently they just come out as a really obvious arc
Good idea, will implement. Shotguns' bullets will probably be made smaller as well.
- if it's not possible to buy a level up because you're too poor, then probably just don't offer it and instead skip that screen
The thinking there is to not start the next level automatically after loading, but I'll consider it.
