Woah
That's simply outstanding. The concept kind of reminds me of Hedgehog Launch game.
Well normally I don't write long reviews, but I want to try it on this. It was a pretty fun game for a while, and has good replay value. Normal mode, on my opinion, was a bit too easy for me, I regenerate health so quickly.
(SPOILER ALERT)
But that was until the boss battle against that mole. He has no pattern of shooting rockets at you, so you have to dodge every one at a random pace. Even so, the battle shouldn't be to much of a burden for you, unless you have bad coordination, but that's besides the point.
(END OF SPOILER)
Expert mode was a challenge for me, but that's what's fun about it. It takes a while, but with practice, you'll eventually achieve it. I hope to see more of you're work, jmtb02.
