The idea is "good" but the graphics need a Lot of work, people will easily get bored by this in the first few seconds. The instructions are extremely easy but the font and layout of how it is given makes it rather "hard" to read. Nice and Simple tower defense, just lacking additional graphics. Great idea though, Perhaps an intriguing plot? :) nice work
simple, but passes time.
Great base! There are a couple things that I think it could use before submitting again:
1) Less repetitive music (maybe a longer loop would be nice)
2) More obvious how much money one has.
3) Grid boxes so the player can see how big the field is and where they can place turrets.
Other than that it was very well done and I think just needs UI changes to be a full game. Nice Job.
Work on the color schemes, i can't read any of the text on the bottom. Also try adding a background to the placement area, and straight lines to the buying area, it would make it seem cleaner, and more interesting. I like the idea of the upgrades though. So overall, clean it up, and make it look nice.
really cool strategy game...i guess?
