Nice prototype with interesting music =)

Your sprites and tiles look really good. I'm not sure about the gameplay though. If you can run past the robots unharmed and reach the end every time, then there is no need to shoot the robots, ever. Another thing that threw me is that if you tap the shoot control, he starts his shoot animation, but if you let go before the projectile comes out, he cancels the attack. This is fine if it is intentional, but you don't want the flash to appear as a secondary animation for a bullet coming out of his fingers if the bullet never comes out. I think you have strong pixel art, and I appreciated the positional audio from the doorways, but you have to think of why those doorways are even there if they serve no purpose. I hope this doesn't come off as overly critical, because what you DID do right shows great promise, and your main character is very interesting. Keep up the good work!

Wonderful job on the sprite animations! And I like how the music changes as you move away from the enemies.

Really nice visuals! The shooting animation looks pretty cool, and a great character design. And the panning audio feels really cool! Not sure why there's landing lag after some jumps, but Im guessing you were planning for another feature.
