We (to be more precise I) had forgotten to turn off the debug mode before uploading the build of our game.
That means all our shortcuts during development could be triggered by pressing certain keys - like F1 or F5. We wouldn't want to spoil the game for anyone playing by accidently pressing one of these keys, so we decided an update was necessary. We didn't change anything else. So it's still the rough experience it was before - we ran out of time as we always do. ^^
I hope you still have fun with the game.
We are planning some more updates after the voting period.
