Nice little game, I like the music and the art is nice. Not a fan of how the fireballs spawn, to me the caution reads as an area I should be avoiding but it seems that they spawn in at my current elevation which is counter-intuitive. Though I assume it's like that because of the wildcard chosen. Other than that the game has pretty good balance, always felt like it was my own fault when I did die.
Had fun with this one. Great work!
