Hmm, bit of an odd egg and difficult to judge!
On one hand, I feel like the games are just absolute insanity with most of the humor just being non-sequitur and too personal/inside-jokey for me to understand. Just feels like I'm reading some kid's cringey/edgy diary or fanfic where they make fun of their bullies or weird discord friends and it's like, I don't even want to make fun of it, it's more like I feel like I shouldn't even be reading it in the first place and it's not my place to judge. Really feels like it is a game that should've just been shared with friends and family, not with the public: it's too personal and inscrutable.
It didn't help either that some of the combat seemed very confusing and overloaded. For example, I died in the very first fight in Jonathan's Adventure 2 and I was surprised to get kicked out all the way to the main menu: it was so overbearingly hard that I just figured it was one of those fights where you're destined to die (and with how confusing this game is, heck, maybe it is?)
I will say though, for as much as it looks like it is kinda low-effort weirdness, it actually did end up intriguing me and kept me hooked to see what the heck was going on. It's like there's some sort of charm and smart design behind its strange facade: almost like a lot of effort went into making it look like it was low-effort despite actually being high-effort, almost like Cruelty Squad or something akin to that. Outsider art, perhaps.
In a way, it was certainly more interesting and memorable of an experience than many other RPG Maker games that I've played, where they usually just bore with way too more generic exposition and grindy fights with no strategy: this at least gets right into the action and provides you with a lot of options! So I will give it that much at least!
