TBH I wondered if it was decreasing, but that was the bar in the lower left? I couldn't tell for sure.

Yea, the 'rate of fire' powerup bar tracks your progress to the next automatic upgrade. If I recall, it upgrades after every 20 kills. The game definitely needs an overall health bar at the bottom as you would expect to see in this sort of game as instead it's more like this tug-of-war with the score constantly going up and down, it's all a little... (a lot) chaotic. I should aim to implement those changes to help polish this off after the Jam for sure. Thanks again for your feedback!
