Really cool visuals! I enjoyed the dithering aesthetic and the music & game sounds. For some reason, it reminded me so much of Megaman Legends, one of my favorite games, with the blaster sound effect as well as the sliding doors you have in-game.
That final jump using all the abilities, dash & grapple, I finally made it to the final capsule, then I jumped to just grab it...Except I jumped too far and fell and died haha, grabbed it the second time.
I think momentum is a bit strong when jumping? Many times I fell because I kept moving after a Jump, just tweaking the momentum should do the trick but Overall I enjoyed my experience with this small demo!
Also, two things I found: the platform afar at the start of the game, getting close to it makes the whole world disappear :o & I couldn´t open the bars after getting the dash upgrade, there was a gold mechanism nearby, but I never managed to know what it did (I think it opens the bars).
Game completion: 11:09.
