The new movement update feels pretty crisp and gives a lot more control to the player. A great improvement over the original release. Plus, the added collision accuracy feels spot on. You nailed it on those changes. It's almost a little too easy for my liking now, so maybe there is a hard difficulty on the horizon? ;) Keep up the good work!
One thing I've had a little issue with is when a drone is directly behind a power-up and you can't shoot through it to get the drone. It might be nice if the power-ups didn't block your projectiles.
