This review is generous for what happened!!!
So, I started playing right, and I was like "Hm, yea. I'll give it a 3/5". And then I got to the final stage and the final creep of the FIRST STAGE the Gorilla froze after I smacked it. I sat there for about two minutes wondering WTF was going on, until I realized that your programming skills are flawed.
All in all, however, for concept it's not bad, but there's dozens of things out there that outmatch you.
