The game looks really good and has amazing potential. I've joined!
You may want to use that CG in your promotion materials. It's pretty damn great, and at the moment the adult elements are not very apparent and they take a while to show up during the game.
I'm not sure about Samus as a protagonist, though. I really like the art and the writing, which I think it would work equally fine with an OG heroine, and Nintendo is very aggressive regarding shutting down those things.
I'll also drop just a few minor suggestions:
- The 'interactivity' overlay sprite doesn't look very clear, I had some trouble locating the pickable object at the end of the cave quest for example.
- The combat system is very cool, but I didn't realize you could expend AP points until late in the game. Some kind of tutorial would have been helpful. There is a combat intro text but it's not that clear.
- Sometimes the kind of floors which are or are not walkable are not very clear. But this is something which I don't like about RPG Maker games in general, so...
- I feel like the puzzles are decent, but perhaps they overstay their welcome a bit. The game may benefit from one or two levers less or one or two dancing fire rooms less, IMO.
- I miss a resting spot. Missing a trap move is pretty brutal and you can easily leave your game in a non-winnable state if you consume your items before a boss fight.
It's still a great game which I enjoyed, so congrats for the good work and good luck with the development
