overall a good game
it is a good game, but I just have one thing to point out that bothers me, the magnet towers are useful at slowing things down, but they do so little damage that I fear to waste my resources on them, specially because they only can gain experience from killing things. suffice to say I have never once been able to upgrade a magnet tower
and I do agree with grailas about the damage, it helps with the first upgrade, but the rate upgrades are just so much more effective
I would like to see towers gain slight experience for hitting the toys, and larger gains for killing them. maybe if the points were scaled up by 100x and points were gained equal to damage dealt with an 80 point bonus for killing, or something along those lines
but I did enjoy it, and it was nicely challenging. refreshing to see some new ideas in the TD genre
