I have played allot of similar games, Slay the spire, Poker Quest, Monster Train and so on, think i have about 20 or so games like this on Steam. I have also made a prototype of this as physical card game that i also took inspection from. So it's just a huge blend of allot of different games.
The core was done under the GMTK Game Jam 2022 so it was made within 48h so the time pressure made me simplify allot of the game mechanics.
