Very cool game idea- here's my feedback.
Challenges: I ran into an error/bug in the tutorial that stopped progression there so I went to the main mode. I could only run on Chrome (Safari didn't work with WebGPU enabled) and I think more descriptions/tooltips would've helped for polish.
Overall I love the style of this game and the simple yet on theme aspect of networking. It goes pairs nicely with the concept of the genre- a refreshing take for tower defence games, well done!
