Well, for a first-time solo developer this is beyond impressive.
Can't say much about the story or the characters, as this is just the prologue, but other than seeming a tad one-dimensional (probably due to how short our time with them is for now), I've no complaints. The writing is good, as is the pacing, the comedy sticks the landing and the worldbuilding happens organically, which I appreciate.
Renders are great, not my area of expertise but I didn't find any problems with them and I've always liked this aesthetic so I may be biased.
While the renders are great and the grammar errors are minimal (a feat that's much less common than one might presume in the visual novel medium), what really blew me away were the animations. Some of the best I've ever seen in any 3D VN, bar none.
All-in-all, truly a spectacular start.
