I'll comment only on this since this was, so far, my only issue with the game. You are, in fact, selling your game. While yes, you may be releasing the "game" itself for free you are locking a majority of the game behind a paywall as many have said prior to me. This isn't exactly reassuring anyone to invest in said game, and isn't a business practice I'd recommend. There are plenty of people who use this site to decide whether they want to invest in a game by playing it before actually investing into it. Locking a majority of the game behind a paywall, and a larger than normal one at that, isn't going to get you more investors quickly.
This can be remedied by simply making both your prices more reasonable and the benefits, well, more beneficial. There are several other games that have a team as well, multiple writers, multiple artists, multiple programmers. The reason they have so many backers, past making a brilliant game (which I wholly believe yours has the potential to be despite what people say) is that they keep the prices for backing within reason and the benefits for those tiers are well balanced. As it stands locking a majority of the scenes behind a paywall isn't a good "benefit" for supporting the game. Even your "secret scene" tier is outrageously high and I can only assume by the description those who invest in that tier get ONE extra scene. That's insane, a game that's quite similar in gameplay to yours isn't locking the main scenes behind a paywall, and on top of that their bonus scenes are locked behind a paywall that is only $15 USD. They have a team quite similar to yours, however the reason that they have so many more backers than you is twofold. Their prices are reasonable, and their main game isn't locked behind a paywall, so this excuse, as well as the excuse of having to pay your team, falls flat when other teams have managed just fine.
No one here is asking you to make a perfect game at the snap of your fingers, we are giving you constructive criticism (or atleast most of us are trying.) and giving you solutions and things that you could do better and can only hope you'll take these criticisms to heart.
Instead of waiting for the "donations to increase" to start improving the game start improving it now. You improve the game now, add the things people have request, taking into account the criticisms that people have brought forth and your investors will start coming in more often. As it stands now, people are most likely hesitant because of how you're running your business model. Give a little, get a little as they say.
