We apologise for the late review:
I like the idea that you have for your game, but the game is difficult to follow since the autobattler aspect is not clearly represented. Updating/changing the autonbattler UI to be easier to understand would be good as there is no tutorial to show you that you need to use items from your inventory to assist your pilot. There are bugs with the items that you pick up from some mobs that are stuck and moving all around the cursor, not allowing them to be picked up. I like the retro 3d aesthetic, and the graphics fit that well. The music in the level is a bit basic and doesn't really feel like it fits the game aesthetic, but I understand putting it there for ambience so the game isn't entirely silent.
Your GDD lists all your team members, but they are not on your itch team for the submission. Remember next time to have them on your team on the itch submission. The art and music design sections are very minimal and could use some more detail on the inspiration and direction of both. Listing more information about the primary mechanics would also be good, as well as UI wireframes for the autobattler at least (which is honestly quite chaotic and hard to understand).
I feel like this game could be enjoyed by many people once a few things are updated and fixed. Keep at it, the base idea and mechanics are solid and a very nice interpretaion of how the game could be.
