Sproggiwood 1.3: Steam Cloud Support!

Added support for Steam Cloud.

We added more save slots: you now have three instead of one. Your existing game will be imported into save slot #1.

Music now plays continuously instead of fading in and out. You can still mute music in the options menu.

Added a warning when overwriting saved games.

Fixed some cases where classes didn't unlock properly.

Fixed an issue that caused fire slime bombs to explode a turn late. This fix also applies to a few other turn-sensitive events.

Fixed some cases where clicks or taps registered twice.
