Hello,
Great game! Reran the game from the start, accidentally went to class on Monday after buying the dress, now it says I need to buy the dress and won't let me progress. Having to start the game over form scratch... again. Very annoying.
Glad you liked it <3 We've been trying to fix that particular bug since 0.4, but we never found it. Not even our beta tester has reported that bug. We will still work on trying to find it and fix it once and for all.
For everybody who is experiencing this bug, I've been told that you can avoid it just by not going to class on Monday.
