We're happy to hear you enjoy it so far, lalalaeti! c:
Sorry to hear that you had to restart everything, though! To save your game, click the 'Save' button between the 'Skip' and 'Load' buttons while playing. When you click an empty slot/save file, you'll still be prompted with 'Are you sure you want to override?' on the bottom left part of the screen. Click 'yes,' and there you have it!
