Hello Loisky!
The only complaints major complaints we've gotten are for the dialogue skipping and some mechanics needing more explanation/labeling. XD
I'll provide some clarity to some things in game:
Mechanics.
Suit Locking: You can only lock suits when you have more than 0 Luck. You also click the numbers, not the locks themselves.
(Also yeah, the mistake re-rolling is a pain, we'll work on that too XD)
Suit Enemies.
Spades: Every time you miss a suit when attacking, he gains a stack of Deduction. When he gains 2 stacks, your turn is skipped during the next round. The freezing luck is like cutting you off from your luck (not destroying it). If you had 10 luck and he froze 3, you'd have 7 to use. Rolling for luck (3rd slot) adds to the luck on the cards (the frozen stays the same). After 2 turns your luck unfreezes, gaining it back (if you rolled a 4 while frozen + the 7 you already have, you would have 11 + 3 frozen luck = 14 luck).
Hearts: After 3 turns you have to give up either 5 chips or 5 luck. Does the least damage.
Clubs: His damage increases each round depending on the coin flip (might be every 2 rounds idk). Does the most damage.
Diamonds: Has a shield worth +6. When attacking with any other suit except Diamond and Clubs, the Luck slot is consumed to destroy the shield (If you roll 5 Luck with a Spades or Hearts, you gain no luck and the shield is now worth +1)
Misc.
The Jester/Joker essentially uses the abilities of the previous suit's abilities.
The Secret Boss is the ominous Bartender! Our programmer did this fight literally last-minute XD (some games based off his Godot tutorial experience).
A bug we have is when you lose a fight and try again (and win) you get sent to the free play screen, so we'll work on that.
Hope this helps!
This is my first game (and game jam) and I'm so happy you enjoyed it. We also plan to keep working on it in the future so look out for any updates :D. Thanks for Playing!
