This game is great! I love the idea of drawing runes/sigils to activate stuff, I would looooove a game where you draw runes/hexes to cast spells/curses etc :D!! but that's besides the point^^"
There is no pause button. That killed my first run since I got interrupted :/ . My 2nd run was my highscore and I reached Wave 37 with 522002$ (so always full risk >:D)
the special spells are really cool, and very useful at the later levels. the difficulty progression is very slow at the start, but great to teach you the game, and 10-20 is slow but later on it's great that the difficulty gets slowly increased^^"
good job!
do you know of other games that use a similar mechanic(and have combat) or would be up to make a game like that :D?!
