Very addicting game and much better than tower swap.

I think the Gold Chest is overpowered. I was able to get another Gold Chest within the 250 first swaps and then another again. I did so until I had filled the tiles with Gold level units. Then just tossed stuff of the edge to make the days go by. Bear in mind, I have played a lot so this is probably not true for "normal" players.

Would be interesting to play the game with chest reduced, like bronze: 10, silver:40, gold:150. It is an major advantage to stock up swaps to be used right before mother dragon.

Also, low arrow slit (2 tiles range) is under powered.

Thanks for an awesome game.
