it hasn't been mentioned in a while but it's intentional MC doesn't have a design, Hyao had a poll forever ago about whether we want more scenes and no MC design/CG's with the MC and other character's or less scenes but a set design for MC with CG's with the character's. we voted more scenes no set design. it is not likely to ever change, I apologize to say.
for recommendations though as DrBadWolf said Lust Odyssey is a good one.
if your ok with non human MC's there's a game that had a collab here called Tavern of Spears, there's also one I follow called Outland wanderer. those 2 are similar in genre to this one but each have there own fun to them.
