Well I really enjoyed the game before it got force-restarted, now it's more and more a chore and not fun. Any progress got really slow and as usual you have to rely on luck to get anything useful. I'd say that it's still on bearable level for me, I get it that they have to make money on this but if it gets any worse then I'll probably quit, or switch to relying only on daily spins. Too bad they forgot that it's best to hook people up first and squeeze money off them later because right now it's really not a friendly start.
A bit of a waste since I liked the art (got lucky to evolve mostly the more human-like nymphs) so it kind of depends on what you pick and as said earlier later stages are generally less furry.
Seems the only useful tactic is to evolve high level nymphs to stage 1 to get boost at as low cost as possible and after unlocking at least two super-nymph slots level them up to 10 from bottom to top (I think evolving only boosts DPS not a super attacks damage).
As for the system requirements - the memory leaks are really big during reloading or rebirth, other than that I can play it no problem on my almost 10 year old laptop just fine: be it on autoclick or background when I'm playing something light (usually VNs) on Steam. For now I'd say that server downtimes are more of an issue.
