Not that great. In fact, I agree with most of the comments.
The music was good, but the actual game was basically a filler.
It was a rather easy game, needing to only hold the up and right arrow key mostly because going uphill was taxing. A challenge would've been nice, but I'm only suggesting. Do whatever you want.
Anyways, the message was nice and all, but it was just a generic love story meeting, which I believe wasn't "sudden". To be fair, the background was nice, but it got boring after a while.
Having some other thing to look at, or a different background would've been nice.
Overall, this game may have some potential, but seeing how it currently is, it's kind of hard to see/believe it has potential. But hey, keep trying. Learn from this :)
