Tria Prima is an alchemy/necromancy simulator. You, as an alchemist/necromancer recently woke up from hibernation, must create yourself a new body to sustain your existence. In alchemy, there are three principles: salt (body), mercury (spirit), sulphur (soul). Combine the three principles to manipulate life force around you. Create rats to do your errands. Infect sewers to increase tombs near you. Explode tombs to obtain the three principles. 

Theme music is composed by my dear friend İbrahim Yılmaz (https://soundcloud.com/ibrahim-yilmaz-770409070).

Special thanks to Daniel Linssen (https://managore.itch.io) for the font and Juhani Junkala (https://juhanijunkala.com) for sound effects.

Hey, I thought this was a fun little thing! I think the pixelly art style and very dark/grey palette work well to sell the atmosphere. If this game branched out into more complex recipes with more ingredients I would definitely buy it.


I'm glad you had fun. Reading your comment after almost forgetting about the game means a lot. I'm suddenly motivated to test myself again with some jams. Cheers!
