i liked the game. it have the old school type of tower defense game (my own definition: without the skill upgrades like increase in money per kill, dialouges (story) and so on; which other modern TDG have).
+graphics wise, it is good :D
+the respawn for the wave is fast which compliments the lack of fast forward mechanics (which i guess is a good style even though i am more comfortable with the fast forward mechanics; just guessing you want to teach gamers about patience :D ).
+the percentage of money drop and its amount compared with the difficulty of the level is somewhat ok. it will really make the gamer think and strategize.
+the mechanics of traps is a cool and unique (base on my experience) experience for me.
**i don't know if after this there still be some editing or the game would be out as it is but i hope this review helps. i have not finished the game yet (due to time) so i guess my review is not yet enough. hoping for a sequel :D God bless :D
