well he first posted about the game on august 21,2017, means this was less than 3 years in development
which is way faster than any western game
especially since this is not a text based game...
tbh i also consider this fast because:
1. lone dev (coding, map design/planning, h-scene idea, animation yada yada)
2. side-scroll (more complicated vs rpgm and other less complicated game, dont mean to belittle them though)
3. side-scroll that is metroidvania meaning more attention to map planning
4. quality of animation
5. amount of animations
6. game is smooth despite the bugs which is fixed immediately
i just wished it has more animations though(probably it felt lacking to me because i saw already most of them by looking at his patreon posts lmao, also reason why its bad to update and show the h-scenes as the release will feel kinda lacking)
Also i wish the game had
- kinkier/more creative h-scenes (double penetration, group sex with DIFFERENT enemies, rougher scenes)
- a more active VA. felt like the VA is a little soft with all that rough sex that is happening lol
- prison-like environment where you can summon any enemy
- bulge, throat and womb bulge. those are some huge dicks entering, it should bulge
- more boss h-scenes (wish the mother brain had some sort of hypnosis shit)
overall im not complaining or anything. game is really really GREAT. probably the best side-scroll h-game for me.
