I really liked the art style, in fact it looks too small, and there is a lot of emptyness above the level, I'd have halved the resolution so that we can enjoy the art more and made the screen feel less empty. The characters felt confusing, I didn't understand who were friendly and who were foe (except the orcs of course).
But for just 9 days of working you achieved A LOT, the mechanics feel solid, the double jump and movement feels natural. I'd probably add something to the combat so it's not just spamming clicks, maybe use the shield with the right click? in any case I really like where this is going, it reminded me of an old arcade game I loved, Wonder boy in Monster Land. Loved the vibe of the game, I wish you don't stop here and keep adding more stuff. Good job so far!!
