very nice game. managed to end up back at the entrance of the cave the first time but that made reaching the end eventually even more fun. Only small remark I have, I'm left handed, and on an azerty keyboard, so WASD is not natural for me. but other than that, a great small thing you made.
*edit* managed to post this 3 times, so if you see more posts made than you actually can see, I deleted 2 copies of this post :).
