Love this. Most if not all of my feedback mostly amounts to some tuning since I think the game needs a little balancing but otherwise, what's here is amazing.
Currently stuck on the 3rd phase, but I'ma definitely come back and try to beat it lol.
But first, there seems to be a bug where if you come in contact with a wall, you stop moving entirely. This was kinda annoying and caused me to take damage quite a lot tbh.
It goes without saying that the presentation overall is amazing. From visuals to sound, it's all great
That said, I think the visual design of the boss could stand out a little more from the environment. I say this because his hands kinda blend into the environment a little too easily. As opposed to the bullets, all of which contrast well and are very readable. This kinda makes the hand attack a little unfair at times ( more on that later .... )
To go back to how balanced the game is, I think the first two phases are balanced well enough, but the third phase could use some tuning. It really made me feel like the player's speed needed to be increased somewhat.
Going back to the hand attack, just an idea, but what if the first hand comes at you from the side opposite to where you are. I say this because I ended up getting hit by it multiple times before I even saw it since I needed to move right to get the green pillar in the attack which had a row of pillars. Maybe just a skill issue, but I feel it's something worth noting
Also, when you reflect a bullet, maybe the yellow stamina bar could get replenished a little ? Just to ensure that you don't accidentally stun yourself.
All that said, I think this is a pretty fantastic game. Great work on this
