levels are completely retarded... one level my towers are completely raping and the cant get past my first two, and the next theres a line of 60-70+ creeps flowing right past em even getting through an army of fully upgraded towers behind my first two, the tower AI is completely stupid, towers don't start shooting until an enemy is halfway into their range. Bosses on the other hand are insane too, first level i lines the road with 3-5 star towers and still couldn't kill him, but i guess as long as you pass a level...
don't play this game with a slow computer... its all laggy and even if your pressing the notes and enter at the right time according to the song, the notes just skip over the space ur supposed to hit them in... makes it so you miss almost every note
im gonna rate 5/5 just cuz i know it could be really fun, and its probably my computer but there is lag between the time i see the circles appearing and when they get close to the outside circles, causing me to miss almost every one. i mean i can hit em OK when i catch on to the beat but other than that it looks like random skipping circles on my screen. some just appear out of nowhere and i cant hit em fast enough...
I found a rather helpful glitch. If you press the number that corresponds to the weapon you are using before it runs out of ammo in its clip, it instantly reloads. But you cant hold the number and mouse button down at the same time, the shots don't register. I'd recommend that you use the musket, not cleaning yourself off, for about 4 levels until you can buy the machine gun. Then use that and the glitch until you get the second to last gun or, if your patient enough, the final gun.
