A lot of those games you listed have sequels or huge modding communities. Kindergarten 2 was pretty good with nearly identical gameplay to the first. As someone who 100% hotline Miami I thought the sequel was such a pain to beat but you should def still try it. (Also wanna plug Katana Zero here). Those games also have *tons* of fan made levels. Deltarune will be completed someday probably. I have not dabbled in Undertale fan games so I can’t speak to quality but there are a ton of them. Stardew Valley also has a ton of mods that add or change things greatly. Terraria has a supported mod launcher you can find on Steam and is probably 3rd in most mods created behind Minecraft and Skyrim.
I have also been playing bloons tower defense 6 an unhealthy amount recently, very fun and not hand eye based at all.
