Got everything, this one is very fun, love seeing all the references, and it's pretty funny. I like figuring out which items you need (or don't) to go somewhere. It's just that the final final ending was kinda disappointing.

The gap between primer and normal sure is something huh
Completed every primer level but the normal ones really make you think hard

Played all 3 routes, and it's actually super fun. Really feels like Undertale. My favorite one is pacifist but the neutral ending goes hard.
