Welcome back! I didnt stay as long as you did, but i hope you stay tuned for a while.
Also, (If you dont know) now is popping the 0.5.1.1 release (the bugs correction mini release of the bugs correction release 0.5.1 of the engine switch release 0.5.0) released today!
And also 0.5.2 for some time from now, like 2 months or so(very potential features: spawn system overhaul, as spawn is just broken, currently you need to die to respawn things; interactive tutorial, and BINDING AGENTS, YES! CELLS CLUMPING TOGETHER!)
Also i think autotroph overhaul might be a feature too but not sure.
(Also custom emoji reactions are broken in the forum)
