Really cool!

I think this could  be iterated on. Looking at something like Tempest where you move down the tube after defeating enemies. The one button combo of shoot and change direction works great.

Maybe add some lives too so you don't have to go back to the beginning after dying just once. The boss has a lot of life and it got demoralizing to retry from the beginning after making it far.

Love its simple yet effective one button mechanics! Fun and challenging. I think it's better to give slightly more time to dodge bullets.

I like the simplicity and graphics. It's easy to pick up and play. I feel like this could work pretty well as a mobile game too, with multiple levels and some ideas expanded upon.

I had a lot of fun playing this :)

Neat little game! Assets work well together and provides a fun bit of gameplay :))

It's a simple and effective game, the graphics are very nice, the life bar of the boss could have been a little better placed and drawn. More diversity in the attacks would also have improved the gameplay. Nice game but not at its full potential
