Not writing a review so as not to affect the rating:
So I played through this for a bit, and it had a really interesting premise.
You are a goblin and you have to sneak around and collect coins (probably dropped by people?), with which you can buy helpful items - though out of a very limited range.
The point of the game is to make a harem as far as I gathered.
The sneak mechanic is pretty simple. Guard sees you, chases after you. If they catch you, you lose some gold and get transferred to your cave. Cool. Note that they will also stop chasing if you change maps - but although that's a bit awkward (I mean guard sees you entering someone's house and stops chasing you?), it's to be expected.
The way you get the girls? You raise their affection by either talking to them or giving them gifts. Every so often they send you on a quest which will then advance their progress. This was something I wasn't expecting, and it was unfortunate that it was so. I mean you are a goblin, and yet you're doing the whole dating sim thing.
So here's my suggestions:
(Note that I'm suggesting only things that are doable with this engine and require minimum coding / plugins already exist for them)
Please note that this is just my subjective view, because I found this game interesting, and it would become more interesting this way for me.
I'm gonna end this here, because I already wrote much lol.
