I join the chorus of praise, this is a terrific start. Everything clicks: the original spin on the postapocalyptic setting, the music, the story and characters, the excellent graphics.
A couple of remarks, also suggested by other users:
1) the cursor is indeed not too practical, it's not always clear what you click on. On a related thing, it would be great if, when you hover on an item especially in the inventory, the game tells you what it is. This is particularly obvious when you buy stuff, as it doesn't say what are the things you can buy if you go over them with the mouse.
2) with so many characters (9 just for the love interests!) it's very easy to get dispersive, trying to do a bit for everyone so that the overall progress is slow. I'm pretty sure you know that but please be aware of the balancing act in the updates.
3) will there be explicit sex scenes throughout the game?
4) another question about the masculine-feminine. When a character is described e.g. 'more attracted' to feminine qualities, does it mean that if you have predominantly masculine qualities you still have a chance to go on his route but you need higher attraction threshold or something like that? or there is for example a limit to how much masculine you can be to have a route on that character? (I can explain with examples, I'm not sure I've been extra clear!)
5) you mentioned in other answers that you struggle a bit with the limitations of the platform you're building the game on (Tyranobuilder), are you thinking of changing it or doing something about it?
6) just to know, how will the funding work? Is the demo free and the next updates for people paying, like on Patreon? I'm happy to pay, for this product, I just wanted to hear what your plans are.
7) about other sites: I agree with others that it can be useful. One of the best ways to reach the maximum amount of people is probably F95Zone (where a page for Ergi already exists), but one has to be able to filter away the obnoxious voices (the community is generally fine but there are the occasional annoying people and the mods don't do much about it). Patreon of course is the next step but it might help having a decent base of people that could support the game before going there (not sure about this, but surely helps).
