Cool little entry lol
Unfortunately I only managed to get till the second boss, but I think the design of this is still good
The arenas were pretty well layed out and kinda forced you to move around a lot with platforms you already jumped becoming inaccessible for a bit, or the boss making platforms inaccessible. I really had to think and strategise quite a bit when it came to which platform I should actually jump to.
Especially in the second fight where it was possible to accidentally exchange my current powerup if I wasn't careful.
However, I feel like the controls could've been better. An example would be using W and S when you're on vertical platforms. Mostly because it got confusing in the heat of battle to find out which key corresponded to which direction
And while the overall visual design is nice and simple, I feel like the boss's healthbar could've looked a little more readable. I really needed to squint some times to read it.
I'm also not really a fan of the homing missiles. With how limited your mobility is, they feel a little unfair at times. Same for the second boss's laser beam which ensures that you'll take damage no matter what if all the other platforms around you are inaccessible.
Still though, for what this game is, it's really cool.
