Thanks! And I agree, the rotation of the player can feel sluggish sometimes (especially with some weapons, such as the Sniper Rifle). For an arcade-ish game like this, probably instant rotation would've been a better choice compared to the 'smooth' rotation I went with in the final build of the game.
I agree with you, especially in late-game - I would've needed a bit more time invested into playtesting to better tune the spawning ratio of enemies, especially past the 3rd boss, when things go havoc!
I think there is a (minor?) bug: to charge to the 100% one battery, you actually need one second more than the one indicated on the bottom part of the battery. For example, if there is "3 seconds", you actually need to hold the mouse button for 4 seconds to get that 100%.
