Great art style and build. Could use a little more depth in both UI and gameplay. The stretching of your jump giving greater speed isn't immediately apparent so it makes it very hard to approach enemies before they shoot you. On the same note, it's impossible to approach an already shooting enemy because you eventually fall into their arrows. There's also a missed opportunity with your jump deleting the 'blocks' where they only delete one with each jump - you could maybe provide more audio feedback of the blocks being crushed for more satisfaction, and maybe having multiple blocks delete depending the strength of your jump.
