This is definitely useful information, thank you for taking the time reviewing my game! :D I'll look into fixing the issues that you speak of.
ps. I took the liberty of playing your game Line Runnr (70.0 score ;) - perhaps you would be interested in another game that I made: https://corpas.itch.io/double-dogde with a similar concept. Feel free to not play and review it - I don't want to completely abuse your reviewing powers if you dont want to xD
