Innovative take on the Tower Defence genre, I also made a Tower Defence game with a twist. Somethings that could be improved, would be:
- The camera movement directions are based on the starting rotation of the camera, instead of the current rotation.
- The car can indefinitely keep picking up more luggage.
- In level two and three there are machines that cannot be reached by the car.
- Near the end of level two it is possible to access the upgrade menus of the towers.
- In level three you cannot upgrade the towers for the first few waves.
- Towers cannot be removed once placed, but maybe that's intentional.
- There is no wave counter.
Lastly, do you know if it's Tower Defence or Tower Defense?
