I love the "Metroidvania? Okay eventually I'll have to find the double jump upgrade right?" "Nah dude here's 3 friggin bonus jumps good luck bro"
I had some difficulty being on keyboard, as spacebar to jump on the same hand as D to move right made my platforming a bit difficult. Maybe if the fall speed was slower I would have had it easier, or if movement was arrow keys and attack was Z or X with spacebar being jump.
I had trouble with the miniboss only because I couldn't anticipate its attack. Audio cue or flashing color before zooming at you etc. Otherwise, the camera pan? Killer. I loved it. Showed you were in for a fight.
Music was awesome. Megaman-esuqe energy through the game I loved it a bunch! Sword could have had a teeny bigger hitbox and the gameplay would have been less dangerous in general since you move quite fast.
Still, it was rad. The story was cool, the cinematic pieces were dope. Just need some polish on the movement and telegraphs and you're golden.
