It's pretty good.
A pretty good game. I think the amount of effort used is really cool, but there are things that could've been better.
Up-sides:
The best things in this game IMO, where the drawings, voice acting and some of the referrences in there. Especially seeing a referrence to Kung Pow was pretty cool and surprising, and Dr Mocka was fun too. The mission animations were mostly only fun at the start of the game. Drawings were similar to the series and had kept the color theme and all, which is good.
Also, game-play worked well and there were different things to unlock and such.
Down-sides:
It gets pretty repetitive towards the end.
Most of the different patsies didn't really say anything fun, and the hench men didn't seem special other than referrences again. Like the VI thing...
The game gets very easy at some point. It starts to feel like it doesn't matter what you do, you get tons of money and have nothing to use it on, missions are all the same, and so are the waves of enemies that you don't even have to give much attention to later on.
All of the bases were pretty similar, I think the music should at least have changed in different bases...
The ending fight was kind of boring, but the end after that was cool.
It's a game with both pros and cons, it had some bugs but they didn't bother me, and it's strength was the small details.
Keep it up!
