I know it takes time and the quality of what he put out is amazing, but the update was still short(I guess for 4 months?). And no, im not even talking about fap material. The games that get abandoned starts in this path, which is the only thing that actually worries me.
Update lengths vary by developer and you can't really use the standard of one developer to determine what is right for another. There are developers that only release once a year. There are developers that release every 4 months, 2 months, bi-monthly, etc. They also all have differences in the quality they release, too. Some sacrificing the higher-quality in favor of quicker releases (or, they just don't have the hardware to do better). As I mentioned, the animations themselves can take a lot of time. For me, we got a good amount of content/changes for 4 months:
New Content:
- Added 1 story scene
- Added 9 events:
- One Ain event
- One kitchen event
- One event at the market
- Expanded Fairy's content (repeatable)
- Added Rabiah's home in the world map with 4 events
- Added a Harem scene (Emilia / Zahra) (repeatable)
Reworks and Revisions:
- d2b (Palace visit)
- d2c (first Queen visit)
- Reworked d2d (Leaving the Palace)
- Reworked d4g (Second Queen visit)
Apart from that...you mentioned worries about abandonment. The games that get abandoned are those who bit off more than they can chew, they lost interest, they didn't get the support they were expecting, or some other reasons. They also often tend to go quiet on Patreon/SS/Discord, etc. The folks behind Desert Stalker are active on discord. They did not bite off more than they can chew. They post multiple times per month on Patreon (status updates, polls, wallpapers), they are clearly passionate about the game, they have over 1,000 supporters on Patreon, and are even active here in this thread. The risk of abandonment is so incredibly low.
They also are thinking long-term. Everything they are building up to for the final product for what I imagine will be sold on Steam. The people who buy and play the final product for the first time are likely going to be blown away about how great the game is, with all of it's story-building, unique settings, beautiful art, various repeatable events that will be available.
I'm sure I sound like a fanboy now...but damn. Who are any of us to dictate for them what is a reasonable amount of time for any amount of content that is completed?
