Ecological disasters spawn randomly, destroying precious arable land and mineral deposits until you build a city and a shrine to stabilize the situation. Each tile except desert can be improved by building a workplace to gather resources. Wooded tiles give you wood, grassy tiles food, mountain tiles minerals, and sea tiles water. Cities also generate electricity and crafts, while shrines collect mana and help stabilize nearby land. Got that? Good, because to beat the game you will need to build a level 4 shrine and a level 3 city. Easier said than done, as each disaster will destroy or rearrange tiles, and erase whatever you've built there.
For such a small game, Tinysasters manages to feature some complex gameplay and even a pleasant soundtrack to boot. Taken together it feels like a rough draft of a more fleshed out title. Here's hoping for Tinysasters 2.0.
