This is an amazing game! The only problem, and this may also have something to do with my internet but it only happens on this game so I think it's at least multifactorial, is that sometimes after I've been playing for a while the game will get so slow it doesn't really function. The bar for air and the one displaying your score both disappear, and the lag is so intense I can't tell what I'm doing. It seems the only way to fix this is to either reload the whole page or pause and "reset cart," neither of which I like to do because they take away my high score. This last time, I was already past my high score at 2000 something feet (but I have no idea where besides that it was between 2000 and 2500, because the meter was gone), and I tried to wait for it to work but I eventually had to end the game with 2 lives left. It was really disappointing because I think I was gonna go really far that time.
The reason for that was found and noted on the BBS thread! https://www.lexaloffle.com/bbs/?pid=77637#p
