Finally did the 15 brilliant challenge - crypts FTW. FYI - build towers from the gems towards the entrances so all towers reach the same level at the same time. Good to have fearful crypts by the gems as well as at the entrance :)
Got the impossible badge - followed guide on down1oad's comment but i didn't save up for kidney failure and went for cheaper ones. Could have done it faster in hindsight but done in 96 days.
Interesting concept, however it does have errors. It says "undefined" when loading a song and saving high score but it does load the songs for me. Needs som tweaking but a good game nonetheless. 4/5
A little something I created: 9-1---1---1---1-----------1---1---1---1-----------2---2---1---1-----------1---1---9--c---3-5---3-5-3-5---------3-5-3-5-3-5-3-5-8---8---8---8---3-5-3-5---------3-5-3-5----a---3-5-4-3-5-3-5-4-4-4-4-3-5-3-5-3-5-3-5-8-8-8-8-8-8-8-8-3-5-3-5-4-4-4-4-3-5-3-5----
Enjoy :)
Dude! You just completed the 99 Dead Balloons achievement in Bloons Tower Defense 3 and won the 99 Dead Balloons badge and 30 points! Great game, now let's see about freeplay...
Quite hard to get the notes just right, but a really enjoyable game. I actually quite like the dance tunes - something which isn't normally done (except in Feel the Beat).
