Nice game! I love TD games, the targeting of spotlight is a brilliant touch to the targeting system for a TD game. The game has a lot of potential.
There are two important bugs: if you go to the main menu(to restart, for example) the round pass and the only way to go back rounds is to close the game (I skipped to round 8 haha)
The other bug is the button next level in the second level, takes me to the same level. I played the second level 2 times thinking that I was on the third level haha.
I will wait for updates to the game! Congrats on the entry!
