Granted I only played 3 levels, but I thought it was too easy for a tower defense game. I only had to build and upgrade about half of the available spots for turrets. Otherwise it is a good game. Great job!
Thanks for comment and feedback. We found a bug and it was too late to update :/ However if you want to play other levels too, we added the hotfix version of our game below comments of itch io page of our game. They might be harder than first 3 levels :) Also new enemies ahead ^^ Thanks again ✌️😇
