That was a good level of challenge for me. Got close to the green square relatively quickly, but wanted to place more towers and just mess around more. Almost lost (I think) because of that, my road got pretty shredded temporarily. I love when things get to a silly level of chaos quickly. Especially in game jams. I feel the game would have benefited from having hotkeys for quick selecting the purchase-ables.
Overall fun experience. Cool concept and nice execution. Keep up the good work!
