Less is better.
Usually when there are just basic movements with the mouse the game play suffers. Not with this game this is the only Smart way to execute this game. I enjoyed the different upgrades (beasts or monsters) that you could pick up.
THE GOOD: Game play was great. This game was an original idea with original game play.
THE BAD: Not much bad to say about it other than I think it needs to be polished a little more. Some small glitches like the caveman appears floating atop the page if he dies.
This game is for casual game play. Not really any reason to try and beat the game. But if you like racking up points then this is a great game. This is something that would sell well for the right price on i pad or i phone. This game could become something special with work.
FINAL SCORE: -1 Playability, -2 for Replayability. A Springy 7 (BOING)
