Thank you everyone who played the demo and added the game to their wishlist. Demo will be deactivated soon but if you haven't finished all the puzzles in the demo, you still have until Monday before it's deactivated.

Changelog:

// changed: jump statements now require a semicolon at the end
// fixed: error messages about using operators with strings
// fixed: string operation order was throwing an error when it shouldn't matter
// fixed: leaving space before a semicolon was throwing an error when it shouldn't matter
// changed: scanlines are now disabled as default, but can be turned on in options menu
// fixed: time now shows 24h instead of AM/PM, because it was buggy on non-english computers.

FIXED: when missing a semicolon in a statement where there is division, it was throwing a 'division by zero' error instead of 'missing semicolon'.
FIXED: when the last line was a jump statement, blank lines were being counted towards the line count when they shouldn't be.
FIXED: in jump statements, not leaving space after the colon was throwing an error when it shouldn't matter.

Previous fonts used for the game, were non-monospaced and it didn't quite fit the aesthetics of retro-computing as well as making the block caret look weird on some characters. They are now changed to monospaced fonts, so now Comet 64 looks sharper than before.
