Fantastic job on the graphics! I would guess that this was a AA game based on the graphics alone. The cave environment is cool and fitting for something Batman-related. The fog is nice too. The visual and sound effects of the bats are very well done. The controls for playing Batman feels super smooth and responsive, the Batman model is beautifully made and animated too; however I was surprised to find that there wasn't anything to do once I got to the end of the cave. The experience could definitely use some more interactive elements (puzzles, enemies, avoid traps, etc). The game experience could probably be improved with music too (maybe the Batman theme?).
I also see this is your first game jam submitted! Congrats on your first entry!
