Getting the last achievements I was missing for 100% completion, the trickiest of which is the purely luck based Ultra Double or Nothing which requires to you win the jackpot at the slot machine. Luckily, if you're holding the (non-ultra) Double or Nothing, you have a high chance to win the jackpot.
The game is called Ark's Wonder Dungeon made by @ShoeStealinStudios
