Enjoyed the demo! Pre-ordered! Defo an unusual mixture of eerie, yet ripe for lewd events. I’m very much looking forward to further exploration and expansion!
I see you’re taking suggestions/ideas. Spitballing:
-Using the breast and ass expansion to perform a threatening display of size (like a pufferfish) to scare creatures away, or out of blocking your path. Or using the added WEIGHT to break through unstable floors to new areas. Or, negatively, prevent you from crossing unstable gangplanks to other areas.
-Shrinking to access stuck doors, as she was unable to in the demo.
-Growing to bash through doors more freely, but at the cost of extra hunger.
-Lactating to distract pursuing enemies, or lure creatures out of hiding. (insert bad catfish joke)
-Venom or toxins triggering a hyper-aroused state that interrupts movement periodically to climax and moaning might alert creatures.
-Mold or some eldritch cursed item inflicting slime-girl; useful for traveling through pipes, if one’s feeling brave.
-A drunken/IQ dropping status that interferes with identifying loot vs garbage, but allows you to coax her through icky/scary areas she’d otherwise refuse to travel.
-Hermit crab wearing loot.
-I think I can assume squids are already in the works XD
-Just gonna say, Highgamer32’s loot angler fish idea is GREAT.
-and if you lean into the horror potential, what about sometimes, randomly, glowing eyes+teeth coming up in backgrounds of the echo scans? Always where she isn’t looking, and gone next scan.
-and you're ripe for a "inconceivably massive thing just out of sight passes by, and is never seen again" trick
It’s darn fun brainstorming how kinks might be used for game mechanics XD. I look forward to whatever this becomes! I think you have a great core concept, and the execution is great thusfar! (and smart, having an expansion reset after each mission. Having to make art for every-single-possible-combination would add exponentially more work)
