Not bad... not really that great.
Bland, stale, platform, shooter. And that's about it.
Couldn't stand playing for long as the game offered very little in differences in the levels. Doesn't really have much to keep you interested in it either. Feels unfinished as well. As for the physics... there's only so much you can do with boxes and a gravity gun as there are only a few chances to actually put it too good use.
In my opinion, this game does not deserve the spot it currently is in.
As well "Ottawa" is spelled with an "a". Perhaps it would be handy to have a dictionary, or to just google the name of the cities you're using.
