Hmm. I get errors on start up for Edge (failed to initialize graphics) and Firefox (TypeError: can't access dead object).

It's pretty simple concept that's interesting enough but could be improved with additional mechanics and level design.
However, this game somehow feels like a downgrade compared to the first Balb: The aspect ratio is small, contrast between the background and character is almost non-existent and hard makes it hard to see, moving through the side borders makes balb fall indefinitely until you jump, and level 5-1 appears to be impossible. Level one also plays twice.
I think these can be fixed and add some sound. Making objects (such as the orb over the spikes) do something like invert gravity could spice up puzzles.

This is promising.
The gameplay is simple and reminds me of Enter the Gungeon, another roguelike. The color palettes are varied but not an eyesore, the psychadelic backgrounds and portal effects are pretty cool but not distracting in gameplay.
For me, the framerate seemed to drop after playing in a fog of war/dark stage, I use Edge and don't know if that affects the performance poorly. Also, the font is a little hard to read either due to low contrast or the line striking through makes the characters hard to make out.

Cute!
The style is pretty convincing of the show and overall, something Homer would probably actually do. Who doesn't want to eat a giant donut (head)?
The expressions are goofy and charming, the background is simple but pleasing to the picture. The ratio of the composition is good.

Beautiful! This looks like it was extremely complicated to make, and it came out well. I love the shade of blue you chose and how the signature/logos blend seamlessly into the artwork.
I've stared at this for a long time, is there a way to the center?

Lovely! I like the cool blue tone of the art, and the way the back light hits the feathers. I also noticed the body pattern has red tones to compliment the eyes. The background is beautiful yet simple, complimenting the birds.
The detail on the panel is heavy but still distinct enough to understand what's there. However, there's a lot of free space on the left that I'd suggest being filled by the panel. Even simply making the panel larger would help tighten the composition and let us appreciate the Yeraz more, especially with the dark colors and lower contrast.
