I have created a small and simple towerdefence game called Simple Basic Towerdefence. It may be a little unbalanced or still contains a few bugs, but that will come with time.
I have already published it on itch.io.

Could you by chance add a possibility to change resolution or windowed mode? It starts on fullscreen and I am pretty sure there are missing buttons. I play on 32:9 (3840x1080) and there is missing everything. 😫
