I dig the anime vibes here. Story was engaging and captured my interest right away, I wanted to find out more about Trout. Unfortunately, I could not get to Chrystollil because I couldn't get past the.. forgot the name of them creatures protecting their young. I gave it countless attempts and am pretty stumped.
The game mechanics were clean and tidy. Especially the grapple hook mechanic. The slowness of the gravity and character were a turn off though. But I am on a crappy laptop and did see the game lag, so it could just be my computer; In that case, the game just needs more optimization. It did take quite a while for it to startup as well, which was concerning.
Overall, you have something good here.
