This game is awesome. The only improvement I could suggest is adding numbers to the critter stats so you can compare between them. And maybe a way to reset upgrades, and possibly a list of all the upgrades?
The only improvement I'd make to the game would be to make it a WASD or arrow-key game. Having to press z and down to control my pig was a little awkward.
Start of Tadpole Mode: Oh, great, just a bunch of 1-point gems.
100m: Oh, hey, a couple 2-pointers. Whoo.
200m: 3-pointers aren't bad, I guess.
300m: Wow, 4-pointers? This... this is adding up.
400m: No, they can't keep this up. I feel dirty getting all these gems.
500m: Is... is that a black gem? Is that a TEN POINT GEM?
600m+: WHOOOOOOOOOOOOOOOOOO.
I can't seem to scroll/change what traps I see. It's stuck on Locked/Poison/Ice. I see the arrows going up and down, but when I click 'em nothing seems to happen.
I don't know if it's just me, but this is one of the easiest hard badges ever. It was kind of stressful in the beginning levels, but getting the king was easy as hell.
This game is amazing. The concept is amazing, the animation is pretty fantastic, and the upgrades are awesome too. I just cannot give this game high enough praise. As for there not being an upgradeable money collecting radius? It adds to the difficulty. Difficulty's good! I'm tired of it when all of the upgrades make the game way too easy to play.
I'm a little sad that this is just a remake of Burrito Bison, but with Bieber. I mean, don't get me wrong, it's hilarious, but it's pretty much a ripoff.
