I see your message!
1. It depends on the size of the update usually, but in general it takes me about 1 year to finish an entire level. Some months progress is slower (like the summertime right now). But I'm back at it, and we expect an update with the gallery for level 5, and 2 new enemies soon (a few weeks)
2. Most of it is femboy, not futa, but futa is fun too. There will be some extra content after level 5 yes, a bossfight, a redo of level 1, a hardmode and infinite mode, and maybe a level 6!
3. Max is a femboy, most of the characters are. they're just very girly boys.
4. I get my support on patreon, and since I am fairly well known the support is very good, I appreciate them all very much, supporting on patreon gets you in the discord as well and I try to keep a positive vibe in the community there as well!
5. Thank you! And why worry about it, they're cute and they're sexy!
