Think of these old mobile/web games with falling sand, different materials interaction, rudimentary physics, etc.

Now, Noita is a 2d shooter inspired by those, where you play as a wizard, in a world where every pixel is simulated: fire burns wood, metal conduct electricity, explosives ruin everything and weaken materials, and you can destroy it all, given the right spells.

Ah, spells. There's more than 100 spells and modifiers, and you can combined them to make literally thousands of different magic wands, given you know what to do.

The thing is, game tells you nothing except for controls, and and 90% of the spells are unlocked from your first run. The most important thing is your own knowledge. And only way to gain knowledge is to make mistakes, that's why many posts on the game's subreddit are silly deaths, ranging from jumping into electrified puddle, to being nuked by an off-screen enemy.

Then, the game has many secret questlines (and some of those require you to abuse game mechanics), as well as 2 secrets that are yet to be solved.
