Knapsack vs Teach the Thief

Your bag is the riddle. You go down into a dungeon and you pick things up. Every item takes up a shape: a blade takes a column, a hauberk a square, a relic a corner. Your bag isn't a list — it's a grid, and whatever you manage to fit into it IS your character sheet. Damage, block, hit points: all of it is read off the packing. Two items of the same family that touch reinforce each other. One lit seam is often worth more than one more item. That is where the descent is won. THE FIGHT IS DECIDED BEFORE IT STARTS No moves to choose. The enemy is announced with its numbers, you pack, you strike. If it falls, the maths was right. If it doesn't, the packing was wrong. DESCEND Nine worlds, each with a rule of its own: the rockfall that seals cells at every depth, the frost that blunts blades, the bone that splits your bag in two. Fights, elites, merchants, campfires, riddles, bosses — seventeen depths, and a different map every descent. THE TREE 293 nodes across seven domains. The fog doesn't hide what a node gives; it hides what comes AFTER. You see where you can go, never what grows behind it. THE WORKSHOP Five bag silhouettes and twenty-three kinds of cell to place yourself: etchings that reinforce, impassable straps, anvils that take weapons only. You draw your own problem. WHEN IT STOPS BEING HARD ENOUGH Forty-six trials with fixed rules — no rotation, no rest, every blow a crit. Twenty ascension tiers. An endless mode with leaderboards. Forty-six achievements. Two worlds are open from the start; the seven others can be bought — and the right to enter them is still earned in wins. Shards never buy power: not damage, not block, not one cell of bag.

Meet Pip: small paws, big plans, and a weakness for shiny things. In Teach the Thief, every heist starts with two choices. Pick two treasures that share a color, a shape, or both, then watch Pip scoop up everything that matches. The trick? Make every grab count—and leave the protected treasure alone. A LITTLE CHOICE. A BIG HAUL. Match different shapes of the same color to collect that color. Match the same shape in different colors to collect that shape. Match both to narrow the haul.
