It is an addictive game, good enough to kill some time. However there are few disturbing thigs : first, the mouse cursor is too white and it is almost invisible as the background is also white. This makes me really fraustrating to control. Having the keyboard control option would be nice. Second, why there are no speed upgrades? The squarrel is too slow and it really needs movement speed upgrade. Third, I thought the mood of this game was relaxing and cute which made me comfortable to play, but the upgrades made the cute squirrel into some bizarre monster. The monsters too lacks the consentiment with the game atmosphere(especially those UFOs). Fourth, the game is too short to enjoy unlocking most of the upgrades. I am not that good at shooting games but enven I could clear the game before only half of the upgrades are done.
I under stand thses guys on comment are a bit frustrated of the game's 'not-know-when-to-die', but I think this game is still great. Actually greatest along the 'running' games so far. Nice and funny graphics, the thrilling speed that makes me never bored, great game balance... still it lacks the fun of upgrades as others said, and changing the game mode once you caught hermes is a bit disturbing.
