What kind of game is it?
Vampire Crawlers mixes roguelike deckbuilding with first-person dungeon crawling. Treat each run as a sequence problem: find a safe route, build a useful curve, then let relics and upgrades turn that curve into a win condition.
Beginner mistakes
Do not draft every high-impact card just because it looks powerful. A deck that cannot start, defend, and bridge into its payoff will lose consistency before it loses damage.
First unlock priorities
Prioritize systems that make future runs easier to evaluate: card information, relic interactions, map clarity, and upgrades that improve consistency across many builds.
