The presentation and all the movement feel crisp and responsive, I'm not that good at platformers but I managed to get all the way through. I didn't realize that I would stay stuck to the checkpoint thing until I pressed down. Not really sure what the context of the Hello message is supposed to be. I did find my way through the glass to the worm fight, though. I liked that you kept your progress of environment elements (knocked down walls, shield disabled) through the checkpoint, but the pace the boss attacks and with so little health it was very challenging to get shots in/ charge up the jump to knock down the shield. All in all, it feels fun, looks pretty good, and sounds nice, I'd like to play a longer more involved level of this.
