Overall, this was a really good first LD entry! Good job on getting something more or less completed!
I second a few of the comments made above - I felt like the narrative arc could have been a little stronger. I appreciate that you tried to thematically work in the randomness/chaos as a like topic of discussion near the end, but you could have started some of that sort of connection earlier to make it feel more cohesive (similar to what someone above said about how Marco's loneliness plotline could have been more clear from an earlier point).
There were several typos. Given that it seems like English may not be your first language, your grammar was overall good! But I would watch out for consistency things - I noticed a line where 'ok' was capitalized two different ways, and occasionally forgetting to capitalize names. Especially in a VN, the polish on your script is really important since that's a solid 70% of what people see! (other than the cute girls, of course vov). It's also not a big deal, but most VNs that I've seen follow the kind of arbitrary grammatical rule that you spell out in words the numbers one through nine. I feel like it makes things look a little more professional in general?
I also think that some sort of way of displaying what the options were with each roll would be nice. In the game, the tale of 'The Fox and the Grapes' was used. But with the rolling, it often felt we were the fox unable to even see some grapes high up, you know?
It's impressive how long of a narrative you were able to do in such a short span of time though, so well done! You probably could have edited a little bit though and polished some of the really good concepts and ideas that you did have though. I look forward to seeing what you make in the future :smiley:
