This game was a blast! I really enjoyed the Legend/Key at the bottom giving me an introduction into the basic tiles and their effects, which helped me to understand how the game worked without a massive tutorial or lengthy explanation. Since you left some of the tiles off of the Key as well, it left room for me to explore and find out what different tiles did. I personally would have enjoyed some sort of system where I was able to choose upgrades for my player, as it felt like near the end I had so much health I couldn't really die as long as I kept going to heal tiles. Overall, I really enjoyed this game and think this was an awesome submission!
