Ignore everything I said below, this is game had great potential when it started but it's now a patreon milking scam. As more recent reviews makes clear it lacks focus, just adding side characters with one scene instead of progressing the main content, so just tons of pointless grinding of affection points for no gain. Can't speak for the combat or dungeons since I remember that being redesigned every other month so who knows what it's like now.
Not been this disappointed with a game since the Incestual/Insexual Awakening devs decided drop their game in the span of one month.
God bless the Koreans cause this is some 10/10 artwork and character designs, milfs and shortstacks for days. With a penetration and a blowjob scene, animations, decent showcase of characters, and a clear direction for how the gameplay will work this is in my opinion an exemplary alpha release.
Key controls (see OP) is something I've seen lot of people complaining about and while it's pretty wonky they're in my experience standard for Japanese games so I understand why the developers choose them. An option for switching between western and Asian controls might be appreciated in the future.
I've seen people complain about the dungeon but in my opinion it was neither too hard nor too grindy (one full run was all that was needed). However, the limitations on attacking (only forward) and moving does mean you have to be a bit tactical. Beyond this I do hope a repair system is implemented by next update, running around with five bats that break in three hits is a bit silly.
Biggest gripe so far is the Engrish: it's not the worst I've seen and it's not as bad as MTL, but I can't say it's good. This is of course maybe the most difficult aspect to fix (can't expect the creator take night classes for a porn game) but I hope the author implements some system for translation feedback or sharing dialogue scripts. As it is now I don't even need a incest patch - it's already unclear whether "Missy" is your real mom or not.
So beyond that one gripe Spooky Milk Life is on its way to become one of my favourites on this site. If the author keeps this up it'll most likely be the first game I've ever supported financially. It's now the first game I've ever supported on patreon since Opala and man, the upcoming designs look great.
