CalcCrawler

The Game

In CalcCrawler you move through a procedurally generated map, fight goblins and bosses, and build your expression from number cards and operators. Every enemy has a target range — your result has to land inside it, or you take damage.

The mechanic sounds simple, but the card system adds depth: every card has a limited number of charges. Once they run out, the card is destroyed. You're not just solving math problems — you're deciding which cards you can afford to use, and whether the new card offered after a fight is worth swapping into an already full inventory.
