The pixel art is fantastic, the cover looks great, the visual effects and post-processing do great leg-work, and those are the biggest praises I can give this game. It lacks a core that dictates all the design decisions that would make the game cohesive mechanically and thematically. It feels like a hodgepodge of game-like-ish mechanics that don't really conform to a tight experience. Game design is all about making decisions, and centering your game on one idea (or a group of closely related ideas) is usually what makes for great games.
Take this in good faith. You're amazing with art and visuals, and I'm sure you can get very very far with more work and practice. Congrats on submitting for the jam! I wish you the best!
