Pretty fun game! I like the pixel art animations. My only criticisms are it's a little buggy and the sound fx are too loud.

Some constructive feedback for you:

• If you jump at the side of a white platform, you stop moving forward and stick to its side. This is a pretty clear sign that you didn't use frictionless colliders for the platforms
• The concept of having to choose the attack based on the color of the enemy on reflex is pretty cool, but you can completely cheese that by just using both attacks at the same time for every enemy
• The sound effects are way too loud

But yeah otherwise this is pretty nice!
