This game is very clean and well presented. Everything works pretty great, except for the fact that if a round starts and you don't have a path tile in front of the start tower, the wave breaks. The timer for path placement is a little annoying; I like the idea of strategically placing a route, but the timer prevents me from putting in as much thought as I want to. In the later rounds of the game where the map is absolutely covered in towers, it often feels like your route doesn't affect your success much, because there are simply so many towers. I like the color matching idea with the towers and tanks, but because you can't manually choose which tanks to send, taking advantage of the system is entirely out of the player's control. Either telling the player what tank colors their next wave will consist of or allowing the player to choose it would be a good improvement. This has been a mostly critical comment but I want to end by saying that this a decently fun, really polished game and its incredibly impressive you did it in 48 hours. Good work (:
