I think I wouldn't actually mind the graphics if the game would work.
I agree with this.
The controls are a bit loose. The collision detections is off. The music is entertaining. And I found one hog but didn't realize that I did.
Also all of this.
Like jbadams I feel that I may have been needlessly blunt, but it's clear that there are some issues with the game's functionality. The graphics are kind of weird, as has been mentioned, but I really don't think this is a devastating problem. If the game were imminently playable, people would look past the graphics; likewise, if the graphics (and interface as a whole) seemed extremely polished, people might be more inclined to struggle with the controls rather than giving up. This is unfortunate, but true: if a game "seems" really professional, the player will probably be more inclined to deal with a steeper learning curve, awkward controls, and numerous glitches, at least to a point (see Skyrim). I'm guessing this has something to do with the fact that a well-presented game makes the player feel like their problems are their fault rather than the game's fault, whereas if the game is less polished, they'll be more quick to dismiss the game as broken and give up. I don't have anything to back that claim up, though.
Anyway, my thinking is that the most efficient route to taking this game from pretty much broken to something that people will actually play for fun will involve making the controls (including character/camera movement, menus, etc.) work as well as possible and making it clearer what the player is actually supposed to do. This will probably involve a great deal of playtesting and a lot of tweaking that probably doesn't seem necessary, because you already know how the game is "supposed" to work. The graphics probably shouldn't be a priority at this point. Spectacular graphics can help to hook the player, as I mentioned, but so will having a game that actually works, and you'll need that no matter what else you want to include.
I think using Coppercube might be limiting you a bit, but I've never actually used it. Still, it has some weird "features" that I've noticed in other things made with Coppercube.
As for selling the game, in the traditional sense I don't recommend it. That doesn't mean you can't try to monetize it, but you'll be much better off putting it on something like Kongregate. People will play a free game as long as it's not terrible and other people seem to like it; getting people to actually pay money to play a game requires quite a bit more.
