어딜 봐도 다리

- Added an additional line to the VMAN tutorial board, indicating that it's an important mechanic - fixed the "atoms until next tier" counter after the atom collider is prestiged

- Made the red teleporter by c5 loop back to the hub, hopefully preventing softlocks if a player happens to bypass one in the chain - Fixed the rare case where toggling omnidash would leave you with the wrong number of abilities - Also, toggling this ability now totally normalises your abilities: if you have an old save with 3 double jumps, you can "fix" that here - Expanded the overgrowth background to fix the rare case where it was loaded in the wrong position

- reinforced save files, and added backup saves - reworked how secrets are counted, so that players can no longer lock themselves out of the achievement by finding secrets while steam is not initialised - increased the verbosity of logging when saving; if there are future save issues, i should be able to find them via log files.

- A whole load of lategame upgrades have had their costs or scaling factors reduced - +1 double jump has been moved from the end of the tree to the middle. - The "omni-dash" box is now a toggle: you can choose to have -1 jump & omnidash, or your previous moveset
