I was alright,
Digging your own path looked cool, but in the end took away in sort of challenge.
Every wave was destroyed at my first corner, except for the ``bosses`` which were handled with the very next corner. I am not talking about a long hallway that corners either, a simple 3 right and 3 down. Overall without the challenge, and very basic graphics with only a few towers and traps this was pretty boring.
Maybe for a sequel, try to gloss it up, you can make squares look good if you try. Also please add a fast forward mechanic, it is extremely dull to stare at a screen waiting for the same few enemies to be destroyed.
