First things first, thanks a bunch to everyone for providing such great feedback on their experiences with the game on launch day! Wonky display options are no good and that's a big part of what this little update seeks to improve.
GIGACHESS V0.82 CHANGELOG
- Auto-hiding menu bar only applies in fullscreen mode
- Fullscreen scales properly and doesn't conflict with the taskbar
- Exit confirmation prompt appears when ESC key is pressed (double-tap ESC to quick exit)
- Disappearing mouse cursor bug is fixed (change window size with R key to restore if alt-tabbing manages to kill it)
- 25-hit Achievements now operational
- Leftover save data from debugging cleared from Puzzle Attack mode progression
Despite how simple it is, cloud saving is doing something silly so we've removed that feature from the store page until it's up and running. It's super encouraging to hear that you're enjoying Gigachess, the game's only going to get better the more time we all spend with it!

EDIT: Cloud saves are go! :3
