Holy crap! That was awesome!
I loved how the three shot system instantly got you into an action-puzzle core loop! I had fun trying to figure out how I could best position my shots while still facing the challenge of moving to execute the plan.
Didn't notice the ammo count until my 4th try though; found it a little hard to read and got me thinking it was time based than ammo based, haha. Also wish that I had more control over the pacing; had moments where all I could do was wait when I played really well.
Overall, loved it!
