for the first hard badge on mount magma it's really easy put a dark monkey on each path infront of that middle lava center next just buy sniper monkeys buy one then upgrade it to pop 4 trust me lead balloons found the gray ones then make them shoot faster rinse and repeat the hard badge is free for the taking!
there's this ridiculous glitch where whenever u try to go to map next lvl or restart it it's just a blank screen and end up having to refresh the page srsly
