Just as the title says, would you be suprised?

A little bit I guess? The only reason I play is so I can chat with friends, the game is too simple for some people and the community in the public rooms isn't so nice all the time.

not at all
it's not what steam players typically play

I'd be the opposite actually

nuh-uh
its pretty un-famous-ish
but i would be pretty suprised if its reviews are mostly positive

Not at all.

The only thing I can think of that people would vote the game negatively is how bad the community is. Granted, the transformice community is not as bad as some games out there, but it still has that one group of players who think that a certain joke is funny, when its actually a serious issue. There's probably another reason, but I can't think of it at this moment (it's not even 8am yet @_@)
Other than that, I should think it would be mostly positive reviews on Steam, since the gameplay is very original, it can get addicting and has competitive play. Not to mention the graphics are pretty good, and that the game can be played even on bad computers

I'd like to say no, but to be honest I probably would be a bit surprised. It's a good game, albeit it gets a bit repetitive after a while, but it's got an interesting game play and it's pretty unique in a sense. Plus the graphics are adorbs. The community is where it falls short the most, I'd say.

If anything I'm expecting it to get funny reviews rather than negative ones.

I'm going to go against the grain and say yes. I think the community is going to spam good reviews because they love transformice and the admins but if it does get negative reviews I will laugh my ass off.
