I realy liked your game and you should be proud of it.
It was interessting and kept me wanting to know more.
the Undertale vibe was immediately clear and i loved every second of it :-D
Also greate music!
Once I got stuck entering "Day 2" (WASD wasn't working anymore), but i don't know how i managed to do that.
Overall a realy nice game and you should explore more in this direction. I think you got a talent for that!
