Not bad
I love the concept of a first person shooter like this in a flash game. I haven't really seen many done like this, and it's a fantastic idea. The concept is kinda lame...mutant hamsters? You did fantastic with the gameplay though. I was owning hamsters all the way till the end, but the boss was super hard. Unfortunately, I was so busy clicking like a madman trying to protect myself, when the game over screen came I must have clicked quit on accident :( Something to keep in mind I suppose in case anybody else does it, maybe you could move that button? :/
Drawings were all great, sounds were amusing, and the music seemed appropriate. The animation was decent, no complaints there, and as I told you, the concept is brilliant. I hope you continue to implement the same first person shooter concept in other games. Don't think I'm giving you a low score either, because most of the score I'm giving you is for the gameplay. The mutant hamster thing I think is a bit cheesy...reminds me of a goosebumps book I read in 6th grade, but honestly I can't think of a better idea for you off the top of my head.
Although the style of first person shooter you created is sweet, I don't know if I'm a big fan of the 'potato gun' either. I'm not really sure that's what it was, just guessing. If you could implement some other weapons you could have a super sick game. Maybe some automatics or a sniper in that style? Just some thoughts to keep in mind. I think if you had a better story other than mutant hamsters and maybe some gore, with some different sound effects and weapons, you could strike gold with the style of first person shooter you've got going. Think like mini-mw2 or halo. That would be sweet, and if you added some medals, I guarantee people would be coming back. That could be top 50 material for sure.
Well, this may very well be the longest review I've ever written...ever...but ideas for this kind of a game just kept flowing, lol. Hopefully some of my suggestions are useful. Keep up the good work.
