1394 is a very high score and yes, the up and down method is also the way I get mine highest score...... Which is a problem need to be fixed in my opinion...
You are right about the controls, I will definitely add them in the next version. I did consider about publishing it on mobile, you know but the lag will be something have to be fixed.
And I will also add some music to the game in the next version. I didn't add one on realse because I was too lazy....
Thanks a lot for playing, I think I will pick a day to finish this in near future...
