I have pld this game a lot last days - and I like it a lot! Only problem is that it is way too easy.
I just played trough extreme in tower 1 and ended up with 6000 spare corpses at the end. Only first 4-5 levels are hard until you get your towers up. Then the rest of the 25 levels are a bit boring since except climbers, no enemies get above my two bottom levels...
The last waves should be a lot lot harder to make it more fun and a challenge!
I also saw a comment from a person asking why towers dont auto level up, and I just found out in my last game that its not always good to level up a plant (since distance of balls get shorter)
so I decided not to level up one of my plants so it would still hit the enemy. Thats a reason for why its good that towers dont auto level up! :)
Great game when u get the hold of it. Havent tried extreme yet, but easy, normal and hard was a little bit too easy. The bombs that destroys towers are easy to deal with - just use the freeze function and I havent got any problems with them.
A tip: As levels get harder you should have made the "footing" thing smaller and smaller. That
would have made the game much more interesting and harder, this was way too easy. At some of the levels you dont need to use the "road" you can just take a shortcut. More obstructive walls can force the user to pick the road to goal that u want.
Except that, its a good game idea. But as said: wud love to see a very small cursor floor at last levels, that wud be harder! :)
