thanks so much for this glowing review! it sounds like you had the intended experience :)
as for steam releases there are links in the credits screen where you can follow my work! my biggest project right now is arcade2000, a site which intends to bring together multiple games like this (from other devs too, not just me) in the best online scorechart system ever. my interactive freeware site is ultimatewalrus,com and if you really want more content similar to Kersploosh! you can check out Vertabyss and Vertico which are the first two games where i was figuring out this 3D submarine control scheme. (i did not reuse their code for the jam as they were different engines, but i did iterate on their design).
