This was really fun. Having to bounce the bullet on the pads to kill the droids or to activate the switch was quite interesting.
But i think the problem with the concept is, that you can beat most levels just by shooting a bunch of stuff around, it gets less about choosing smart angles than more about just trial and error until you hit something, and some things requiring multiple bounces.
I think part of the problem is that the droids are actively moving towards you, which would make sense for a traditional shooter, but i don’t think it works well with this kind of concept. Maybe a predetermined path they are “patrolling” would be better, so that you can be sneaky and shoot them around corners etc. In generally I think this could be a great puzzle game if the levels are designed a bit differently.
It would also be great if you change the color / particles of the bullet for each bounce that you can get some feedback how much you hit.
