Beautiful game, plays well, sounds are great. Only bad thing i could say is that on my first run, the level generated in such a way, that I couldn't get back to the wizard lol. Great job!
Sorry to hear you got stuck! You can hold "R" on the keyboard to teleport back to the surface if you get stuck (although you lose some of the chips you've collected). Apologies I forgot to include this in the in game instructions
