Game is good, though I have a few critiques.
There's a thing where getting a "Try Again" doesn't spend your money when there's still monsters available, I'm assuming this is a bug.
"Try Agains" in the early-game worlds are too common to be fair, and it would have been too hard to complete the island if it wasn't for the bug I mentioned earlier.
It would also be nice if you could de-superize creatures in case you don't like their design.
There should also be an in-game guide that shows you how to preform certain mechanics, such as muting & time-warping creatures.
Some games are too repetitive, one example is RunnerMan. The level is always the same, which is detrimental in a game focused around minigames. I'd recommend adding randomizers to make the minigames more varied.
Other minigames tend to be lacking, such as the infection one not providing much other than adding more "Zombies", and JumpingMan Lives Again would better be suited with keyboard controls (The mouse controls are a nightmare).
For minigame ideas, I'd recommend playing virtual pet games (A good one is Moy, that has LOTS of minigames), and arcade-based flash/web games (Some good ones are based on existing media, licensed by companies such as Nickelodeon, Pokémon, Cartoon Network, etc).
