The amount of sprite glitching made it extremely hard to tell when an enemy blew up or not. Projectiles are hard to dodge, especially once bosses start throwing out homing projectiles.
I kept counting 5 colors on-screen, despite it sounding like you used GB Studio for this. Not sure how that happened.
Though the ring section made me go "Oh no, is this Superman 64?" for a second, only for the game to go a completely different direction afterward. Kind of a funny little bait and switch there.
Definitely noticed some spelling errors, as others have mentioned.
The green background for the text box during parts of the story had lackluster contrast with the text, making reading the story more difficult than it should have been.
With some polish, this could be a decent game. But it's current state was a bit underwhelming.

can you show me where there are 5 colors. and I did use GB studio. if you want to check I even put the GB rom as an extra download, and here is the Github repository SpaceTimeWarrior/TL-Hyperion-War (github.com)
the export is to monochrome. with SGB active (for changing the color palette of the whole screen). this was to prevent accidentally doing 5+ colors. the version I used is 4.1.3 (this version split the singular project file into multiple smaller files and create prefab objects)
where you playing on mobile as only the top part is a part of the game screen if that is the case as the lower section is for an emulated controller
here is a picture of the editor with a preview of chapter 2 as well as the first part of the endless mode as well as the first chapter which is in the jam. the red is collision, the orange is triggers and the purple are actors. this is zoomed out so, most of the actors are not visible except for a purple rectangle. the only one of these that has anything visible is the actors
this is a closer look at the first two levels as well as the Hud before it is retiled to what is visible in game as well as the intended ghost version of Blair. I didn't fix that because it kind of looks better.
