Thanks a lot for the feedback! We added some gameplay options such as the ability to set a damage multiplier for the enemies so everyone can enjoy the game :)
Maybe your son can try it out on the x0 multiplier (when Alex is hit, they only get the knockback and no damage).
We are having a blast with the reception, and I am really happy you considered having your son play Raider Kid. For me, personally, this homage to the Game Boy era is an attempt to have the younger generation take a look back and see how people built very well-designed games back then, and that is not just adult nostalgia haha
My son is too young (less than 2 years old), but I hope we can play Raider Kid with him in the near future.
