Hi, here's an update on how Subell's Abyss is developing, and some information on the currently planned scope of the game. I'm a solo developer and only work on the game in my spare time, but there is still a steady stream of content being added.

Subell's Abyss is currently planned to have:
18 large interconnected areas - Done, but most need additional props, art, and mechanics.
5 unique enemies per area, total 90 - Halfway done. This is what I'm working on right now. I can crank out one every 2 hours or so when I have energy.
1 boss per area - Done!
Final boss/Secret bosses - Not done.
Randomly generated passive relics that increase your stats or trigger effects - Done, but likely needs a balance pass.
Undetermined large amount of weapons - Currently around 30, need many more.
Undetermined medium amount of skills - Only have around 5 right now.
10 to 20 random events - Only have one right now.
Progression system - Mostly done. Defeat bosses to get keys to unlock more of the world. Need to work on some overarching progression after unlocking all connections in an area.
Shop system - Done!
Quest system - Still in the design phase.
Online Multiplayer - Maybe. It appeared to be working at one point, but is pretty broken right now. I'll make an effort to see if fixing it is viable at some point.
Performance optimization - Game runs decent when there aren't too many enemies/projectiles spawned in, but needs some optimization for larger groups.
So, quite a bit of work remaining. I'm optimistic though, since most of this is just adding more things I already have a workflow for producing. I'm also expecting to have a little more time and energy to work on it soon, which would help immensely.

I also posted a few Youtube videos and shorts about the game over the past months. Here's one of a witch bossfight:
See you next time.
