Push the limit. Leave room to survive.

Chain Reaction is a turn-based roguelike deckbuilder about making a few card slots do extraordinary things. Build Heat, stack multipliers and unleash your chain from left to right.

Created for the VAI AL LIMITE (Push the Limit) jam. Every setup card takes a slot you could use to defend, while enemies hit harder each turn. Preview the outcome, then decide how far to push.

Build your winning chain

• 30 card types. Combine attacks, defence, repeated hits and elemental infusions.
• 3 slots grow to 8. Defeat bosses to expand your chain.
• Six regions. Six bosses. Choose your next stop; the other branches close.
• Health carries over. Plan your recovery. The music speeds up when you are close to defeat.

Your first combo

Charge → Amplify → Barrage
