"I don't claim to be an artist, writer or programmer"
In that case, I'd say you did rather well; I enjoyed this game more than I initially thought I would.
I didn't encounter any script errors or crashes.
There are indeed some typos and such in the dialogue--just like in every other VN/game that I've played (some of which were not necessarily cheap, either). I could almost make a living out of providing corrections. :/
So, I'm definitely looking forward to an update. I want to see what that "magic milk" will do to those girls!
