Too short and too easy. Even before grinding I was never in any danger of dying and when I did grind it didn't take long enough that it even felt like grinding. I haven't played this game long at all and I'm already maxed out.
The enemies were decently varied in look, even with the limited attack patterns possible. Visuals were pretty crisp, I never had problems figuring out what was going on. Voice acting wasn't grating for me... it was silly but that was the point. This game does seem to be voiced by just one person if the credits were correct so it could be a highlight reel for their resume; I don't really care about that. The voices were at least distinct between the bear and the bunny. The game has a personality, but doesn't take itself too seriously. The fourth-wall breaking was never so egregious to me that it felt like pandering for laughs.
@Sharpnova - The bear just sounds like a couple of guys from Queens, to me. Not sure what you were trying to say but it's probably more offensive to tell people how they'd feel about what you were going to write than even what you were going to write. Review the game, not other hypothetical players.
