Spik: To be honest I'm not a big fan of the character design style! Stripped-down stuff can be good but I think it works best when it exaggerates features etc instead of just making kind of generic blocky stuff, and it also looks a little out of place with higher-resolution graphics. What a dick crit huh because this forum could do with some more non-RM games but whatever! Also I think something more colourful/visually engaging would be more fun to explore than a grimy sewer thing but maybe that's just me. Possibly it's just because the main character and the interface in the topleft look like they belong to a different and more stylised game than the block stuff.
I mean if it's a more gameplay-oriented project you might want to ignore all the above anyway because I think a lot of games here get bogged down in trying to perfect kind of trivial graphics stuff and it's always better to release something imperfect than to continually rework it to please some anonymous internet nerd, but since you asked
