~*~ What is this?? ~*~

Rocketbrob, a chubby orange creature riding a rocket

You woke up in a blocky world full of creatures. You can't fight them yourself. You can, however, convince them to join you, and then fuse any two of them into something that has never existed before. That's the whole job. You are the Monster Synthesizer now.

Wander huge voxel lands, dig into caves, climb towers, make friends with a sentient flame, then fuse it with a moth made of stained glass and see what happens. Bring your friends. It's free. There is no catch. (There is a chubby sulking legend that blasts off before anyone can mock it. That is not a catch, that is Rocketbrob.)

Available for Windows, macOS and Linux. No web version, sorry, you have to download it like it's 1999.

☞ The monsters wandering around back there have things to tell you. Point at one! ☜

Host your own server

macOS: the builds are unsigned, so the first time you open it, right-click the app and choose Open.

Running a server:

./mon-server --save world.sqlite

Set the MON_PASSWORD environment variable to make the server require a password:

MON_PASSWORD=hunter2 ./mon-server --save world.sqlite

Joining a friend's server: in the game, go to Join a game → Type an address and enter theirs (like myfriend.example.com:7777).
