Very solid entry, great music and audio. Nice graphics. I liked the idea of shielding from traps however it doesn't work consistently - sometimes when jumping on some traps with shield pointing down I "reflect" the damage but other times it kills me which was frustrating.
I loved the way you implemented save points - it made me want to try again after dying to a trap. Also the potions as reward is a really nice element, makes the player risk in order to gain more "attempts" later.
Great game!
