For a stealth game, it's not secretive at all about the horny lewd gameplay. ;D
Speaking of the gameplay, it's pretty great! All the inputs felt snappy and responsive. There is clear progression when you gather treasure.
I came back a few times to play it again while writing this review, and could see myself playing again after updates.
For lack of a better term, naked mode is a great feature. It's a neat way to naturally raise difficulty and hype. The fact it effects gameover screen is just a wonderful silly cherry on top.
I really like the aesthetic and character design. I want to say the character design reminds me of 60's anime or cartoons, but I cannot for the life of me find an exact example of what I mean. But it stands out, looks good, and is aesthetically on point with the classic pixel style and limited colors. The scanlines and very slight chromatic aberration is also very cool!
On ways you could improve:
More options. I would like the option for changing keybinds. Having optional scanlines might be better for some.
A better win screen. Happy but naked is fine, but maybe happy, naked, and holding the main treasure? I went through all the effort after all!
The pearl room itself was anticlimatic. There were neat new platforms, but no dangers. You could do a lot from basically add a few guards, cameras that switch on and off, to creating a whole escape sequence.
The stock moans; already mentioned by another, but I offer two ideas: Either ripping lines from old anime/cartoons or taking the sounds you have and bitcrunching them to match the classic gaming soundscape.
