The developer came up with a way to attract more attention.
The release of Hollow Knight Silksong has attracted a lot of attention, and some mechanics have caused heated debates. For example, not everyone liked that Hornet takes damage from simple touches of enemies (without being hit by an attack).
The developer of Soulgrave drew attention to this and decided to boast that the damage rules in his game are not like in Silksong:
«There is no contact damage in Soulgrave. You only take damage if you are hit by an attack or fail a mechanic. Share this [video] to scare Team Cherry».
Then he clarified his attitude towards his colleagues and reduced everything to a joke:
«Silksong is a great game, as is Team Cherry, and I'm just kidding. Contact damage is definitely a different and valid approach, but I think it's still worth discussing. If you are interested in my game, add it to your wishlist».
