Congrats, the game shows a lot of promise!
My personal feedback and what I'd like to see:
While everything is shaping up very good, I see a lot of potential on the unique "capture and escape" scene that happens with the spider after it drags you into the hole: segments like that could be used instead of a "Game Over", to keep the gameplay flowing instead of reaching a sudden stop, making the struggle of the protagonist more "real" without a force restart. This will allow you to also increase the damage dealt by the enemies and the relative difficulty, without the need to restart from a previous point.
There are very few games that do this and it would be quite unique and powerful if done right.
