i am taking into consideration these various problems for the next update, currently:
powerups like bombro wouldn't do that weird "lag" in the next update so it should be much more fair cuz it actually would hit when it's supposed to
respawn bombs have a planned rework to give a point to being a bomb, they are also effected by the above change
the ice breaking is a bug, same with the flight with bio (but not the hyperspeed)
metal mushroom might be getting some tweaks
