I really can't shake just how much there appears to be a jack o' lantern-esque face on the side of that ship.
Faces aside, one of the demakes where the carefree doodle nature felt very complimentary to the existing castle crashers style/flow. It kind of makes me wonder about making a game in the future where as an extra unlock/secret unlock is to be able to play the game with the rough doodle art of the game. I think that'd be neat, and also maybe terrible to play in terms of readability and contrast haha.
Actually does any game have that as a thing? Feels like a lot of work to basically swap out the entire game's assets all over just for it. With a game boy project, actually making an entire clone of the project, then replacing it would be how I would most likely go about it. Similar to how different language versions back then like german or french Pokémon are their entire own carts and specific roms.
Ramble aside, happy with how Castle Crashers turned out!
