This game could've been better if there were more to the game itself. Perhaps some choices (like Walter doesn't kill himself, for example) could make the game more fleshed out. The gameplay only involved holding down the right arrow, and nothing more, which isn't necessarily bad. You can make a good visual novel with only simplistic game controls. But, this kind of story has been done time and time again. Also, the grammar in this was bad enough in my opinion that it ruined the atmosphere for me.
That said, I do think you can make a better game from this if you spent more time on it.
