Addictive
To say the least, it's one of those games that can keep you entertained for a good 1, 2 or even 3 hours until you get all the medals. Even though it was quite sad that you don't have anything to spend the 300k money after you have bought everything.
Maybe include some extras that cost something like 50k money each? Like deleted levels, from where you had the idea from and why, small things that aren't necessary but that would be interesting.
Overall, great game.
