Spent the 10 dollars on the game and I was hoping for more. I like the tsundere redhead but the game doesn't really go real deep into her story yet. I like the black dude though I thought he was funny but the game does need a little more work. Overall I think the storytelling is decent but not a whole lot of sexual scenes right now so hopefully they improve that in the next update
This version is 0.4 (that is, it is just the forth update release of the game), it will take time for stuffs like that. Maybe in time, plot for tsundere Noriko and black guy Macumba will get thicker, The next update is mainly focused around Noriko's Mom Yasuka (based on poll results from patreon). Anyway this is a one time purchase, so not like you gotta pay more in future for new contents.
