This was such a fun game! The endings were entertaining to get, and I got all 16 plus all the traingles/fractals in about 2 hours (all endings I show in the video as well). Although frustrating at times (especially the bird ending) it was well made and well worth the time to play. The controls reminded me of Getting Over It to some extent, though they were not nearly as intentionally frustrating as that game is.
How to Be a Tree is random but worth it, if you're debating downloading it, I would recommend for an hour or 2 of nonsensical shenanigans!
