This is one of the slowest idle games.. ever. It's so...freakin..slow. This was the hardest medium badge I've ever gotten. It should be at least Hard for time involved alone.
Skool is waay too hard. I ended up writing a program that I could just type in the expression and it would evaluate it and then type it into the answer box. Only way I could get a 100 combo.
The physics need work, you can do the exact same thing 10 times and 1 of those times you'll fall differently and make it across a span. It appears to expect you glitch through the spike obstacles. It's a good start but needs a lot more work to polish it up. 2/5.
Very good game. to beat level 4, just keep building goblins/centaurs until you get to the creeps that are high enough to afford minotaurs.I built everything at the bottom of the lanes.
Try refreshing to see if the problem goes away. If it doesn't, please send me a screenshot of your build.
