I think the reason behind why games take a long time to load sometimes is because they're big games with lots of data so loading "loads" all those little bytes of data for you to play (This is just my opinion).
When I first played Submachine ( IDK what number ) on gamenode, I literally DID'NT know what to do so I stopped. Now I'm back to test myself...
DEAL WITH IT
 "Bloons TD 5"){kind=icon}
 "Submachine 10: the Exit"){kind=icon}
