Aside from that, what do you get? A fairly easy and short game, because it's a demo, it's only natural, but also a incredibly good-looking fangame. The visuals are very cool, the musics are awesome, the effects are cool. Once in a while, I was letting my character die at a random trap or hole, or a spike, or anything, just to hear the game over sound again, because it was good and funny at the same time.
The camera movements are awesome, zooming in and out whenever it's needed, the touch saves are cool and fit well with the lack of a gun, since using a gun just to save is pretty much pointless imo, the gameplay itself is great, and the level design is incredibly good, never getting cheap with the occasional traps, since they are well-placed. There's even a cutscene to show what a certain switch unlocked! This game is very well-thought in the smallest details.
Or at least almost all of them. I have one warning for whoever wants to play this game. If you had to close the game for any reason, start over. Don't resume it. I'm serious. This would be a much more serious glitch if the game was longer, but it doesn't even take 15 minutes, and that if you're not in a hurry to beat it. As it is, this glitch doesn't do any major harm, so I won't take many points out for that. There's still the fact that it's a demo, though, I can't give it a higher rating.
It saddens me that I have to review this game as a demo, but it's been up for more than one year without updates, so I doubt it'll be updated again.
Warning in advance, you can see it from the difficulty rating, but you won't get much challenge from this one. There's one could-be-precise jump at one of the last saves of the game, but as a could-be-precise jump, it's still easy.
Would still recommend, just for the experience.
