Fun, but very hard. I tried a bunch of times but I wasn't able to make it past the first level.

I found myself wishing I could walk around the platforms, like they were planets - oftentimes I would jump to the small edge of a platform, and then there was nowhere else to jump to (since the platform I just left had disappeared), and I couldn't move anywhere so I just had to tank a few hits until the previous platform reappeared.

Also, the boss's health is white on a light grey background. Maybe make that a different color.

Tried several times and only won a couple times. It's a neat idea that I had some fun with, but it could use some polish. While the controls are responsive, I think the camera panning around the way it does kinda screws with them since it means your endpoint is always shifting. The bosses probably could've used better difficulty progression, and it was slightly annoying that they'd always get out of range while you're being shot at. It also felt a little buggy with the square occasionally detaching from the platforms for no discernable reason. Could use some work, but I like what you've got so far.

Really interesting concept. A little bit too difficult for me but I think that just may be me not being the right target audience for a highly difficult game. The core mechanics were fun when you get a hang of it, but having to constantly balance moving on the platform and trying to line up the shot while keeping an eye on the terrain changes/enemy movement was a bit clunky or overwhelming for me. That said, hitting the shot felt so much better because of all that. The audio fit the gameplay perfectly too.

Interesting concept! I found the game very fun, when you are able to think a path and hit the enemy just in time is really satisfying!

In my opinion there is something to polish in the controls. They feel a bit inconsistent at times. There is a bug where the player character start to floating around that happens quite often. I encountered also some various visual bugs.

A little side note, the tutorial is good, but I didn't understood at first that platforms has a sort of cooldown after you leave them.  I didn't immediately understand it because in the part where you explain that using a platform as an obstacle that block your path, there's a bit of space on the sides. After some attempt I went through there XD

About the graphic I like the minimalist style, I don't know if you plan to change that in the future, but I think that some small adjustment in the UI could improve the visual impact a lot. Just some little change in shapes and colors. For example, the slider below is hard to grasp that is the enemy health bar and clash with the other game element.

Overall the game is very promising and fun to play. I loved sounds and boss abilities! And for me the difficulty is well balanced, it's a nice challenge but it never becomes frustrating ^^

Mechanics

The jumping feels rewarding but sometimes the jump path disappears. Clicking isn't always responsive and can cause you to die because you need to be able to move quickly. 

I love the arcade feel and look. The music and sound effects are superb. The boss was fun to fight and I didn't realize that you can kill the homing enemies until my 5th or 6th death.  I think a small tutorial on beating the different enemy types would help them feel less like the game is cheating and feel more prepared to handle the boss.
