**NOT FINISHED, ONLY 2 LEVELS, BARE UI, NO MUSIC, MESSY CODE**
The idea of this game was to make a tower defense game which was more like a puzzler. You'd get a set amount of towers and a single stream of enemies which you have to defeat to finish the level. Combining towers of primary colours yields towers of secondary colours which are able to shoot their respective enemies. I was also playing with the idea to make a spitter which could reverse such a combination, giving back the primary colour towers, for more flexibility with puzzle creation.
So this took me a lot of time, and it's not finished. Disappointing, but I did learn a lot. For now you can play two levels and that's it. Maybe I'll get around to expanding this idea somewhere in the future.
