Excellent feedback. Really helps... Glad you liked the bounce shots. Definitely the point. I will look to add power-ups in a future build but they will be gained by some kind of shot trickery (Kind of jumping to replying to different feedback, sorry)
I have to take a look but I have made the post-build too easy in hopes of balance. It might have made it easier to naturally learn the mechanic if more difficult. Either way I will implement some more info/tutorial organically.
Right now you move this keeps the opponents from moving but hard to notice because they can just shoot instead. You can pretty much avoid the enemies and get to the boss without having to disable the enemies shot.. This is done by HOLDING down shoot...If you hold down shoot while moving you will basically freeze the enemies and move freely. Doing this in theory kills your control bar so you can only do it in spurts but not not doing it should (again ideally ) make it near impossible to get through the level.
This means finding a balance where you can't just move and shoot as much as you would like but need to balance this with being able to "control" the enemy by essentially disabling their ability to move and/or shoot.. As more enemies are added some might be uncontrollable but you would have to find a way to control them maybe with a certain ability / power up.
Thanks again!
