Kai Magazine (developer)
There are claims that assets (sprites, backgrounds) from Kai-Magazine games are stolen/heavily inspired by/scraped from other games, Deviant Art, and so on.
Metal Dragon, Life on Mars,, THe Secret of the Four Winds, Death & Lead are concerned (at least).
Actually I do not find this utterly shocking as long as the whole game is not done this way, but so you know before buying the games :
This is not simple copy/paste, to me assets seems edited (at least adapted to Megadrive palette), of course the games are not free, but neither is the process of publishing a physical edition. I am not sure they do a lot of money (if any) from this business. Blaze could be in a less confortable position with the Evercade cartridge : surely it will have an impact on future collaboration between them and Kai-Magazine.
I am more concerned with a potential usage of AI, but I do not see any evidences of it.
Let's wait for Kai-magazine's answer, the best one would be to acknowledge it faithfully and add credits to the wronged artists
