Man, this game is hard. Seems like walls are more of a suggestion rather than a hard stop haha. I was only able to kill a couple mummies on my best attempt. Not sure if you can actually beat the level or not.
Nevermind, came back to this and was able to win :). Actually pretty fun once I realized they wouldn't destroy your walls if there was still a way to the exit. Was only able to use ice effectively once, seems better to just avoid it most of the time. Also, some of my tiles would randomly disappear? Made it pretty difficult when my maze would randomly get holes it in letting them through. Great game. Really enjoyed it!
