I need to hire a sleepy boy now!
That's a pretty impressive entry for your first ever game, since the artstyle was pretty good looking that fits very well with the story vibes - except the character sprites that were more pixelated.
This game does very well something that some newbie developers (and sometimes expert ones) forget to do: pacing and personality during dialogues. Each scene didn't feel to overstay its welcome (there were some that went a dialoguebox or two too long in my opinion, but it's not such big of a deal), with some little events that helped keep the player attention just enough (eg: Masaki falling asleep in a scene). And also you could see the characters personality pretty well in the writing of the dialogues - that helped a lot to keep my attention up and not get bored.
The story is... very simple. It felt right for the cozyness of the artstyle and dialogues, but I have to say that the story was lacking any "hook", something that would make the player look forward to the next events. It's probably the only main problem I could see in the game (I did not feel particularly engrossed to the game and not really curious of what would happen next) - but seeing it as a cozy game, I'm not even sure if that's a problem at all for this game specifically, but it's surely a thing to keep in mind while making games.
After all, again, pretty good work for a first game. Masaki the sleepy boy is so cute.
