hard mode changes

starting up the game you could press any key except for the Escape key and it would switch it to hard mode but a lot of new players were continuing to play on hard mode and would wonder why they were losing their progress I had put an indicator in the levels as well as in the menu but it didn't seem to help.

(FIX) so I changed so it doesn't do that anymore. you have to manually switch it to hard mode now. as well as improve the indicators.

PS I'm currently in the process of fixing achievements so hopefully in the next couple of days I'll have that fixed

DM me on Twitter if you have any ideas about improving the game or if you would like to report issues that you've encountered or bugs you've encountered.
