i've noticed a glitch in Flash that sometimes causes the program to freeze up when making certain sounds. strangely, it doesn't happen if lots of sounds are made quickly-but for this game, it can make you miss the second note!
i clicked the face, then i clicked settings...i got a message that flash wanted to access my webcam. i said NO...and now it's impossible to get the title trasher badge?!?! (ps: i do not HAVE a webcam)
first improvement: TELL us EXACTLY how fast we'd have to complete the level to GET the thunderbolts!
second improvement, make it possible to use A & D LIKE IT SAYS YOU CAN IN THE INSTRUCTION PAGE!!
guns towers use up metal when they shoot, floodlights and tesla coils use energy. this is one reason lvl 8 is too hard-not enough time to stockpile enough energy and metal. oh, and having to use energy to make a power plant? bad...
ok, how fast do you have to finish to get the thunderbolts...and WHY didn't the designer notice that the moving obstacles make it IMPOSSIBLE to finish that quickly?!?! (i've only gotten them on the first 2 levels)
the "combos" can be confusing. there are many possibilities, but which one is actually used depends mainly one WHICH TURRET FIRES FIRST; so if you understand it, you can control which combo is used by upgrading turret ranges selectively, so the one you want is first to see the enemy. (mines are made by one combo)
the economic system is screwy: instead of all being updated at once, the different resources are used produced at "staggered" intervals: so first the farms use energy and make food, then a few seconds later, the power plants produce energy-very confusing and annoying.
there's also not enough time in some levels-especially 7+8-to build up defences before the first attack!
