My first impression: nice style but boring.

The game is ok, mechanics are good and the style is very nice, but the characters and story are flat and probably more for children and people who don't listen to it anyway.

So, i will recommend it to everybody who wants a chilled jump and run game, but not if you look for a deeper experience.
I myself, will stop playing from here, because it doesn't look like it's getting any more interesting.

solid game elevated by it being entirely made by one guy.

Kinda feels like more of a puzzle platformer at times than a Metroidvania (was apparently pretty heavily inspired by Metroid Fusion so the linearity isn't surprising) but I'm honestly perfectly okay with that. The game is a blast to play and has some nice lore to delve into for people who enjoy that like me.
