The game is brutally hard, but I'm guessing that's by design. I've only played the shack, and it was brutal until I discovered the gun vending machine on the other side of the shack. Then it was pretty good. I'm scared to move to the caves with all that the comments have stated about it.
What I'd like is a progressive gallery. Nothing fancy, just a dress up and monster select would be enough for me. It's hard isolating a single monster for a few seconds of ideal watching. Gallery mode would need invincibility as well as a kill switch for both quitting and killing mobs to enjoy the pregnancy/parasite content. Right now I'm using Cheat Engine and selectively killing mobs. It's very tedious, but I like the dress up aspect. My only other option would be to make the ideal outfit and then use OBS to record it. Not as fun, but for now that's the only option. It's too hard to play one handed.
I read in an earlier post from a non-dev the idea of releasing source. Instead of a full source, instead just release project files but require the extracted content of the purchased game. I remember reading that it's possible to decompile Unity games, but I've never attempted such a feat. Mainly because I still haven't looked at my Zenva courses (Full time employed + 1 part time, so no personal time, school loans amiright?) for Unity, so I wouldn't have a clue on where to begin editing in the features I want. Plus it feels wrong decompiling a retail game :/
As for getting pidgen holded as an hdev. My sister worries about that. She is an artist and she has two accounts at most art websites. One for the 18+ stuff, and another for boring stuff. I personally don't think it would cause you any trouble. You wouldn't put it into a project folder for submission. My current workplace doesn't even ask for a portfolio for our DevOps. You just need to pass a few basic programming tests. Our systems are programmed in PHP, Python, some other stuff, and a bunch of web sounding stuff (angular, node, full stack, some other buzz words, etc?). As a C/C++,C# dev, I don't do well other there and I just do in house tools.
As for a Steam release. Steam will allow this game on their site. I've purchased quite a few hgames from Steam. My favorites are Meltys Quest, and most of what Kagura translates. I prefer Steam over DLSite since Steam is usually uncensored (with a patch). If nothing else, try and see what happens. They charge a 30% commission so adjust your price up to 8$ to cover for that if you're dead set on 5$. I didn't like making an itch account since I'll never use it beyond this purchase.
That said, 5$ is a steal. Pixel art games are a rare breed and pixel art hgame are rarer. Not looking forward to losing a pixel art programmer to the bs that is 3d. I've only seen a few decent 3D hgames. Most are just cash cows and/or never completed.
