Oh I know, don't worry about the delay, props to you for fixing it. Played the game and I think it has a potential to be a good runner, the generation of obstacles is a level above me, well done for the game and the quick fix!
If you want I could tech you I'm happy to expand knowledge I also spawn and delete tiles as the player goes through the level so that it saves memory and frames don't drop.
Nice, I was thinking that had to come into consideration at some point. I might just take you up on that offer in the future when I'm planning to add that to my game :)
