The Lag. Fix it.
I would be interested to try something like this, but when the lag is too big to play even at the main menu, then it's not worth trying. My computer is not bad. The problem is at your end. I can't see any other explanation for a 3,2KB game to lag this much than problems with the coding.
A lot of the reviews are about the lag.
Are they not enough for you to do something about it?
0/10 because I can't play it. The main thing a game needs to have is the possibility to play it. This doesn't have that.
Now, since lag is a problem that can be fixed, I'm not giving this a vote until it's fixed. If you care, PM me when it's fixed. If you are not interested in fixing it, then you are in the wrong bussiness.
