Great idea!
It's very, very trial and error, but it's still a very fun game. AP is pretty slow to accumulate, but maybe that's a good thing.
A glitch, unfortunately, ruined my gaming experience. Y'see, by the time I got to the worm right after the two sentry guns, I died from the worm once for not moving. No lie, on the second try, I sprinted ahead, shot twice behind me, and chucked a grenade in the bottom right corner. The timing was so perfect, that the grenade exploded and destroyed the worm in the bottom right. I had survived, standing on the crate in the middle, boss's health was depleted, explosion animation, sound effect, all that jazz...but it told me I had failed.
...What? I killed the worm and lived to tell about it. How did I fail?
I retried the game from the very start. Frustrated I couldn't repeat my lucky grenade hit, I devoted that 1 AP to the other pistol...and in my continued frustration, realizing I'm having a pretty bad time with the FIRST BOSS, I basically rage-quit. One thing I can't complain about is it's certainly not easy, so the challenge is a plus!
Additionally, it would be most useful if you could remove the targeting nodes after you've placed them, instead of having to restart and maneuver your way around level again. It's a pretty brilliant system, with how it's layed out, and it does a good job not to over power Hank...but perhaps he might be a little underpowered.
The atmosphere, characters, and all-around artistic style looked awesome! Sound effects were all good, and the music was appropriate for the mood, but not very interesting and never grabbed my attention. As far as programming goes, it felt very nice! Hank was reliably weighty, and I pulled off the wall-jump well, the targeting system is accurate, and I suppose disallowing targeting nodes to be close together makes sense for recoil, but they should still be easily removed should the player make a mistake. And what's the deal with those grenades? Was my boss mishap a similar result to SangerZonvolt's (below me) deal?
I'm still voting highly regardless of it because it was a good lookin', good feeling game, with a good idea; it's evident you guys spent some time on this. Happy belated Pico Day! Voted 5.
