Hello! I just released update v2820, which contains a few bugfixes:

• Gauntlet (co-op): Bomb-throwing enemies now target a random player, instead of always targeting player 1
• Gauntlet: Dying with coins on the floor and restarting the stage now makes those coins disappear, instead of letting you grab them on your next run for some free extra points
• Gauntlet/Dungeon: Fixed a bug where unlocking and selecting a high difficulty level in Dungeon mode then switching over to Gauntlet mode would let you play that difficulty level in Gauntlet mode without unlocking it, and vice-versa

Thanks for supporting Chessplosion!
