Recently, the demo version of Codex Mortis was released on PC on Steam. This is another variation on the theme of Vampire Survivors, but there is a nuance in the approach to development.
The project is positioned as the "first 100% vibe coded playable game", i.e. all the code was generated by request with a neural network. Art, effects, sound, etc. are also made by artificial intelligence.
From the point of view of the gameplay, Codex Mortis is a bullet hell in which players will have to use the "forbidden powers of death" to fight the flow of undead. It will be possible to mix spells from several schools of dark magic:
Collect 5 ancient pages and defeat the guardian of the portal before the immortal Lothar tracks you down.
