Congratulations! You found all the bugs and unlocked Bug Hunter badge :D
The "7" skill is working in the code every time, but UI for it has 2s delay between activating it and stats windows updating.
It was last minute fix for sound looping bug that was present only in exported version, but not in editor.
The fix was to put 2s timer and stop sound after timeout signal and that's from delay comes from.
The bug for playing again was spotted after uploading the game and is caused by the fact that we forgot to reset game state when starting new one and it's crashing.
It's all fixed already and waiting for jam to end to upload new version.
Here is your reward: While in Main Menu tap on keyboard: "iroll20". You should hear the short laugh and now you have 7 lucky dices and you are invincible.
Thank you for playing!
