This is a single player 2D survival sandbox game,.

You can create and destroy terrain, and synthesize props.

The game includes content on analog circuits and supports packaging basic electronic components into chips. Non electric doors are self generating, and improper use can cause explosions.

You can use an anvil to strengthen equipment and fuse multiple pieces of equipment.

The terrain may obstruct your view, even in 2D games.

Attack behavior is often related to collisions, and the speed of collisions can affect attack power.

Some monsters can also destroy and construct terrain.

The sales opportunity will automatically refresh the product after you make a purchase. The vending machine you place yourself will not refresh the products, but it can earn you coins. NPCs who purchase goods are very fragile, so try to protect them as much as possible.

You can place automatic turrets to assist you in attacking monsters, but be careful! Automatic turrets do not distinguish between enemy and us, they hit whoever they see.

Pipelines can extract items from storage boxes, and their triggering relies on pulses rather than high levels.
