Going through the specific things that need a response, in order:
-There's already a custom notes system in the map menu, so you can leave notes in any square of the map saying whatever you want it to say. That should more than solve the issue of helping you remember where "gimmick" locations are, eh?
-You are correct that the Torguis' H-scene content is Coming Soon™. Our animation pipeline is, unfortunately, far behind the rest of the game - there's a LOT of missing H-scenes, enemy animations, and NPC animations. We don't earn enough on Patreon for our animator to go full time, so unfortunately it just keeps falling further and further behind due to a lack of time for him. We've been trying to catch up for over a year now :' )
-The slimes also have a duo scene, so it's not just the sentries. I do definitely plan on adding more duo scenes, but I don't plan on doing them with different enemy types right now - there's no possible way for us to add scenes like that for every enemy pairing, it would be far too much work (I think it would total to something like 120 extra H-scenes), and so the decision for which pairings to have would end up being completely arbitrary, and it's just kind of an awkward thing to deal with. Besides, once the game is complete there will already be over 30 unique enemy H-scenes (every enemy gets, bare minimum, a unique normal and BE H-scene, and many of them have duo scenes planned), along with all the CGs and story H-scenes/CGs, so we certainly won't be lacking for content!
Anyway, thank you very much for the kind words! We have plenty more planned for the game, so hopefully we'll be able to take that elusive top spot
Well, there's been thirty seven versions so far, and there's still one biome to do as well as six enemies and maybe two bosses not to mention adjustments and polish to existing game assets, so enjoy what you have since my best guess is the full release won't be until the end of the year.
I have to admit that there's not a chance we're releasing the game this year, there's simply too much left to do. CPE's been in development a lot longer than I would've liked, a large chunk of that being due to inexperience, and an even larger chunk reworking older content that was really low quality due to the aforementioned inexperience. Now that that's all done, and we're focusing almost exclusively on new content, the pace of development has increased DRAMATICALLY. It definitely does feel like the ending is in sight, but it's still a good ways off, and I'm certain 2020 is not possible at the quality level I want for the game
