Great entry! There was a lot of content and it took me a couple tries to get through it all.
A note on the controls: instead of having an "attack" button and a "switch weapons" button, it would have been easier to play an "axe" button and an "anchor" button. If you moved the jump to "up", you could even put these as J/K and remove the need for M and make it a bit more user-friendly.
