Ugh
Well, i'm really not the guy to downvote stuff, but this pretty much encompasses all the things I dislike in TD games.
1. No indication of the enemy path direction in game
2. Turrets/resistance systems poorly explained, information only visible after click
3. Tiny boring play area
4. No restart button
5. Extremely limited starting options
6. Flying enemies
8. Turrets with very similar effect excepting element type
I really really dislike the game, sorry
Good graphics though small
