Ah nice!!! I enjoyed this! I love the concept! The art was "ok" for me until I fullscreened it, and I saw they were all little guys and then I got really invested haha! :D Nice! I also love the mechanic where you lose abilities; when I discovered you could wrap around to the other side of the map I laughed so hard, brilliant! :D
I did end up running around in a circle holding the spacebar in the end though, it was too much effort to set up a strategy and keep it viable so I went for the lazy option. I think with a few tweaks this game could really kick ass though, if I may be so bold as to make suggestions!
1) I think it would help if the damaging you abilities part was demonstrated a lot earlier, I didn't really notice the damage particularly until later which is a shame 'cos it's an awesome mechanic and it'd be great if it came into play more. I'd try moving the damagable parts out more so they're around halfway down the road, so you lose abilities more easily, and can perhaps manage without them for a while until you can repair them. Currently they're very close to losing health so there's no trade off, you either lose abilities and then health, or you're ok.
2) I like the repairing turrets mechanic, but it made it hard for me to strategise their position as they could soon diappear, so I ended up keeping them close together so I could re-arm them easily. If they didn't diasppear and just fired less often instead I could have put more thought into their position, and also panic-repaired different directions for more firepower when I needed it.
But yeah I enjoyed it a lot, I love the little vandal guys, some guys just want to smash up a big brick with a heart in it huh? And the music was brilliant and is still stuck in my head, I love it so much! Good game, thank you! :D
