Man, i love this game, it's exactly what i was ages looking for, but still in a very early stage. If u're willing to make this a long term project, and is interested in any kind of help, please let me know, i cant support with money but i can help in other ways, just let me know.
Let me list some ideas and improvements i think would be good to your game:
-It may be kind of obvious, but people love vídeos, images, scenes... despite the captivating story, adding some images and scenes would be a nice improvement.
-Grinding. Not everyone likes it by itself, but grind doesn't need to be heavy, nor monotonous, or a softlocker (It can be also naughty, wich is pretty captivating). Grinding can be pretty fun, and If the player truly hates It, he may be able to overcome issues with raw skill.
-Beyond, archangel, gods. It would be very fun to be able to create alliances, rivalry, and even love relationship with other deitys. Not all deitys want to evolve more and more, so some would be open to trade power, creations, build mindsets, planets (from upper gods), fun or anything that can be sold. Also, having an army of lesser angels, slaves, a harem, or whatever, could be very interesting.
-Demons. Okay, this may have an impact on the story itself, so thats just something to think about. Demons are known by many myths for being an evil Race that seeks the most deep and degenerate human feelings, so it correlates to the evil aspect, but evil gods are still gods, and still have their angels and archangels. The Eldritch (for what ive seen of the story) are corrupted beings that tried to free themselves of First's aspect. What if the evil aspect gets strong enough to surpass First's aspect? It could make the multiverse into a literal hell, but of course it wouldnt want to stop there, as there's always room for more, so what if First's multiverse is not the only multiverse, and there is a multiverse where evil is stronger than reality itself? And that evil First (or whatever is the stronger being) send his demons through the multiverses? What if there is a Good aspect thats stronger than reality itself? What if that good First is able to create multiverses with other Firsts... Anyways, lots of ideas for the story, even If u dont like it, It may cause some ideas to pop in :)
-Soundtrack. Thats something of extreme importance in the game. Nice musics can captivate a Lot of players, they can inspire in action moments, make u calm while ure resting with ur archangel, or whatever.
Well, i know these are really hard features to add, but im willing to help If u want, im sure this game has a Lot of potential, i Hope It turns into an even more amazing and complete game.
