Some notes after playing through much of the content.
BUGS: Penis is repeatedly misspelled as "Pennis". Itzel seems buggy; she tells you to come back tomorrow as it's too late if you visit her in the afternoon, but is available in the morning and evening. Also, after Itzel's BJ h-scene, it always goes back to that scene, so I'll presume it doesn't properly get marked as played so you cannot work for her and progress her story any further. I followed the instructions for the base upgrades (buy them in order of cost), but still ran into a bug once I bought the bed; the futon worked fine and I got scenes with the futon, but then when I purchased the bed, going to the spot to install it simply replayed the message that this was where to install base upgrades; I couldn't actually install the bed and progress the base any further.
IMPROVEMENTS: Beyond that, it would be nice if the "h-scenes" would trigger some way other than going and talking to women after "working" twice, and h-scenes really should advance the time. This is particularly notable where there are scenes in MCs bed, which you only trigger by talking to another character, then it's nighttime for the MC in his bed, scene happens, and then it's back to whatever time of day it was when you initiated conversation- be that morning, afternoon or evening. Also, the mom's arrival seems out of sync with other story progression; for mom's storyline to make sense, it should "trigger" based on progression with the aunt's story, and other progression scenes for mom and aunt should be dependent on how far you've advanced the other. Lastly, it would be really good to add a status screen showing affection progress and replay for prior scenes.
Pretty good game so far, just needs some polish and it has great potential!
