Spectrum TD

The damage needs to be increased on towers across the board. By the end of the game you've got so many towers,(the damage boosts don't stack by the way), that the game moves at a crawl. Also, the delay for each tower is wired backwards. When a creature walks into range the timer starts, THEN it fires, it should fire immediately then delay should take effect.

So, damage boost across the board, retool tower delay timers, stacking damage boosters, and a speed up button.

The game seems to have a lot of potential, but there are a few things it still needs:

A fast forward button.

A button to control some of the effects you've put in place, as the game is extremely laggy even when nothing is really happening.

The upgrade ring is nice, but it's frustrating that you can't see any stats of towers you can't buy, so planning ahead is impossible unless you remember them all (this is a td, not a memory game).

Currently somewhere between 3/5 and 4/5, but it has potential to go between 4/5 and 5/5.

Needs smarter turrets. They focus on one, and even the towers that do no damage, and serve no purpose rather than to lower armor for example, will focus on that one until it's out of range while several other mobs pass it by untouched. And they should target the first monster that comes into range rather than the one with the lowest health (or at least I think that's what they're doing.)

Please add a speed up button.

Interesting upgrade system, but somehow I find the overall game... dull. This might be because it runs so slowly from about level 20 onwards, and may also be because there is no speed-up/fast forward button.
