Thanks for the review, fren!
I tried to reproduce the crash you mentioned but I couldn't get it to happen again, but I'll keep looking into it.
Regarding the crafting mechanic, it is balanced by the limitation of 3 cards per forge, and by the -High quality crafting gem- requirement, if you can break it regardless of those roadblocks, then you should be able be broken as a reward.
The Wizard's class ability is deceptively useful. I made it this way with 3 scenarios in mind. First, in case of you being low health before an enemy encounter. You can skip the enemy to prevent risking losing, and instead skip to get to a resting place, merchant to buy potions, or maybe even a luck event. Second the ability gets much stronger once you level up in the main menu, giving the Wizard loot as if he won the battle when he skips the battle. Lastly its also there to be the class of choice for people looking to get a record time in beating the game.
Your point about stats is valid. However Dexterity also has direct impact on the battle giving you extra cards in your starting hand, and giving you a higher chance of starting first as you mentioned, which is actually quite important on the later battles (and after higher amounts of successful runs which increases the difficulty) .
While Luck and Intelligence don't have a direct impact in combat, they both are vital to craft strong cards, and to obtain more money to get strong cards and equipment from shops. (Luck increases drop rate for crafting gems and gold, while intelligence improves the selection of effects you have when custom crafting, and lowers the prices when shopping) In my mind you have 2 combat stats, and 2 deckbuilding stats. But it is a fair concern. I think that the more successful runs you have, the more you will need the non-Strength stats (Or at least the more you need to strike a balance among all stats).
Again, thanks for your comment and for playing, I hope my explanation makes sense!
