It's been a long journey to get here, so thanks for sticking it out with us! We hope we've worked out any major issues, but please let us know if something strange pops up.
The Steam launch is also the official introduction of our save file transfer system, which can be accessed directly from the file menu. We're working to bring this to Android and iOS by the end of the month to enable full cross-platform support between all versions of Soda Dungeon.
