The indicators are circling around the player
The indicator for dashes is a rainbow segmented ring around the character (you can have up to three). The number of bullets indicator is indicated by small little bullets going around the player (you can have up to 8). However there is no indicator for how much time until the next dash or bullet is about to recharge. I have experimented with that as a UI element but couldn't figure out a way to implement it without it feeling too cluttered.
Thanks for playing my game though! I hope you enjoyed the experience
