very interesting! i don't have the patience to go through and try to get a bunch of endings, but for the time i played this was a very interesting and unique game. the art style is nice, and it's fairly easy to understand what to do. i know tons of ads tend to be a problem in mobile games these days, but i don't think the ones in this one are overbearing. plus, i kind of like the way they announce an ad is about to start. definitely recommend.

It's an absolutely charming story with multiple endings and simplistic yet engaging gameplay. A truly wonderful experience all around, plus I got to learn about some new foods during the process. The only complaint I could possibly give is that I wish there was more, which is more a compliment given how much there already is. 5/5 Wish I could experience it anew once more.

I've played this game for two days straight and I can confidently say this is by far my favorite mobile game I've ever played. The writing and characters is done so well that it really is hard to stop playing, it makes you want to see every dialogue option, every ending and just explore every aspect of the game. Not only is the writing good, but the concept of this game in and of itself is very unique. After getting the true ending I am very glad I've spent my time on this parasite :) 11/10
