Thank you for kind words and valuable feedback. I am glad you liked my game.
The visuals were inspired by early 2000s and '90s games. mostly by strategy games of that era.
responding to your notes.
I didn't add information about clicking on towers, because I thought it's obvious. Now thinking about it, people who don't have experienced in TD or strategy games might not think about it. It's a valid point.
I thought about returning money for destroyed buildings, but I am not sure how good it'll fit the economics of the game. Maybe I should try it any way.
You can speed up game with arrow keys. The reason I didn't mentioned it because game in development and I sometimes forget to match variables(like cd) with global speed. I could inform about such option with an additional warring.
Yes the credits and option menu are pretty raw. The idea was "it's better than nothing".
