I'll be completely honest
I encourage everyone here to support Eluku if you can.
His work is of such unparalleled quality, he more than deserves it.
I'm going to be a bit more realistic about his work quality, as the games themselves are pretty janky and the art style isn't the exactly the greatest compared to many other games. However, he does all this alone and embraces many unique fetishes and circumstances, so I give him a lot of leeway for that.
That said, though I'm not against supporting my favorite ero game developers, I very rarely pay for promises. If a developer never completes a game, they usually never get my money for that game either, so unless Eluku's pace significantly increases because of the revenue stream, I'll pass and would rather wait or simply not see the game ever finished if he's going to continue crawling at this pace despite getting support.
Unfortunately, all too often giving a developer support for an unfinished game actually has the opposite effect on development, as it doesn't take a genius to realize folk will happily pay you way more than the game's full release price over time without having anything reven remotely close to a full game, and in many cases, droplets of progress every 4~ months is even enough to keep the money flowing. Of course, the infamous "remake" trick works too, usually involving a complete rewrite of the game or unneeded upgrade to a slightly more updated engine.
There are a mind-boggling number of stalled patreon projects, many with (empty) promise, some of which have been 'development' for years beyond the expected timeframes with very little to show for it. I know a lot of people like to argue that what's there is worth the asking price, and hey, that's an opinion they're free to have, but I'm not going to pay several hundred dollars for a $15 game that's 10% complete and is already five years in development, no matter how good what's there already is.
More and more folk are getting wary of this now, I wish Eluku all the best if this is his plan. I'm just going to set the game aside and come back in a year if he doesn't dramatically speed up now that he's getting paid. We've been on this silly arena for way too long and imo it is by far the most boring part of the game, like a discount store fairy fighting without any of the great monsters typing with varied animations/fetishes from fairy fighting.
