I like how I have to dodge and strategize what moves to make at the same time! They are two different styles of gameplay and having to do both at the same time presents a good challenge. The boss's attacks are fun to dodge and have entertaining variety. I also didn't come across any glaring bugs that impacted gameplay. I think the art has room for improvement and a different song could fit better with the gameplay, but considering that you seem to be specialized in programming and developed it on your own in well under 48 hours, it's really good!
P.S. I checked out the other games on your page and the one called Doggo is really cute. :)
