Tower Defence River Defense Go Hack 1.4 + Redeem Codes

The game itself has all of the fun mechanics of a tower defense game. Kept me entertained for a decent amount of time before I had to tear myself away and go back to work. It is rough around the edges though. First, the game never told me how much upgrades cost. I had to figure it out by myself, and then keep track of that. That's annoying to do and an easy mechanic to add in, even if just as a quick blurb in the help section. Second, I was able to have -10 currency at a few points during game play. Third, the health system is a bit different than other games, and you should tell players that before starting the game. Multiple enemies got through during one round and it only counted for one HP. Fix these simple things, and you'll have a great game on your hands.

Needs a nuke option and faster money so more towers can be built faster.
Better towers needed for the flying. Only level 77 obtainable

That and the graphics are blurry and the game plays way too slow.
