My feedback for Realms of Mind (or is it Realmms of Mind?):
What your game does well:
The art is vibrant and colorful when the player is happy. Disgust is expectedly off-putting in its color and scenery. The soundtrack for each world fits the emotion it's based on.
The character moves a bit fast on keyboard controls. If it's lowered a little, the player might be able to have more time to enjoy the scenery as they walk.
What your game doesn't do well:
The theme of this jam happens to be the name of a Disney film about emotions. While your intention was to base your levels off of each emotion, you only did that with their scenery/soundtrack. The gameplay is still just a first-person game with platforming segments.
The dialog felt unnecessary, especially the hints of 4th wall-breaking. One player could interpret it as humorous, but another player can interpret it as a lack of confidence to offer a unique play experience that can separate itself from its source material.
The level design of 'disgust' is really difficult for the point in the game at which its introduced. The player has to jump to and from sinking platforms, has to stop and grab an item on one of them, and turn back around on that same sinking platform.
Areas of Opportunity:
If this game is based off of Disney's Inside Out, the biggest opportunity is to make emotions the core game mechanic. A game that does this really well is Super Princess Peach. I recommend referencing that game for some ideas. What's more is, like your game, it's a platformer.
Platforming segments from a first person view are hard to pull off as a developer. If you already have an in-game companion, it wouldn't be a stretch to give the player's character their own body and move the camera to third-person view. That way, the player has a greater perception of their surroundings. It'd be more comfortable to navigate.
I hope this feedback helps!
