Cute little game! I like the risk/reward sort of thing going on, where you had to decide how many treasure chests to drop off.
A couple notes:
* I wish there was some kind of indicator of how much a treasure chest reduces your jump height. I would throw treasure chests to see if I could make it, but it's a very imprecise science, and the bounciness of the treasure chests was more frustrating than fun.
* I wish there was a way to "place" instead of "throw" treasure chests. That'll give you more precision, and then you could easily do things like bounce off of a treasure chest lid to give you more height for a jump (rather than just throwing it and hoping it lands near the end of the platform).
* It wasn't immediately obvious to me that my torch was dying, or what a dying torch did (does it keep bats away?). At first, I thought it was a bug in the game, especially when the torch fire particle effect kept playing.
* There's a door at the bottom of the first level that I couldn't figure out how to unlock. I figured I would buy a key from the shop, and then I would need to go back down to the bottom to unlock the door, which would take me to the next level. Instead, the shop just magically teleported me to the next level, which leaves me wondering what the door was for.
* There should be a sign above the door that leads to the shop indicating that the shop is there. I didn't even notice the shop the first time I walked through the door into the actual level, so it took me a little bit to realize I had to head back up to find the shop.
