The game feels really easy, and when it's hard, It's REALLY hard (Farmageddon. Just, Farmageddon.). Mot of the game was just me mashing the Z key and moving a bit so I don't fall to my death. The items are pretty useless, and some of them actually HURT me! (The cannon is the worst offender.) The AI is also so dumb. I usually get killed by the stage hazards than the enemies. Hell, I sometimes feel the stage hazards are my true enemies. However, I do like the concept of this game, and I'd like it if it was finished, so I give it a 2/5.
Here's a tip: Don't grab the golden bloon powerup unless it has a sun god icon on it, which looks like a gold monkey with a crown. The sun god powerup hits all bloons and ignores immunities, and is the only one to do that. + to keep this alive.
