About Project Stack

Project Stack is a game about expanding a small floating island by collecting and selling fruit. You earn money from your sales to buy more land, with the goal of meeting a quota of 1,124,240 bits.

Grow your island

Buy tools and upgrades to gather larger stacks of fruit and improve your productivity. Your island changes and develops as you expand it.

Manage your fruit

Watch out for fruit that rots: if left unchecked, it can spoil your stacks and set you back. You can also find unique elemental fruits that interact with each other in interesting ways.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
