Amusing. Finished it off and I wish to offer the following:
Tadpoles that kill bases almost instantly? They need to go.
And the level with the huge base? Never have I needed a joystick for a flash game so badly.
Difficulty is spotty, upgrade system seems to need a certain path, and cannot be reset (that I can see).
The randomness sometimes makes for impossible jumps (IE: Hit the bomb or land between the next two buildings and fall to your death) but otherwise pretty neat.
The multi-part boss fights are annoying, the animation is too choppy (a second a frame for animation is just plain too slow) and any game with poor controls and jump puzzles really should take a look at how annoying it is to play.
However, you did try with the animation, and it's not a terrible attempt. 3/5 . . . Now try to do better next time.
Not a game, something which could be found out with a simple Google search or high-school math, and really, REALLY pointless.
I'm only not flagging it because I'm not sure it's disallowed.
Actually, based on the contest for which it was created, and the fact that you can run along the outside and just wait for more bulls, it's not so bad. Still 3/5
