maybe I'm just a fanboy for tower defense games but this has a lot of potential, where this game goes wrong is the balance, you get too little money for the enemies you kill and eventually I just died because I had too few towers(a note in gamemaking: always make the game easier than you think because new players will only play it once or twice and they wont have nearly as much experience as you do). also I was very confused about the walls, in the end of the game I had well over 100 walls but I could only place a handful at a time. but the concept is good and there are a few unique ideas (unique to me). the artstyle was a bit basic but you can still make that style work if you do it right. overall a great effort, I can see alot of work went into this, well done. my high score was 613
