Good graphics. nice towers... looks like fairytale. Upgrades? 1. keyboard shortcuts for building, upgrading and selling.
// 2. Time acceleration button or variable speed slider or something. and send next wave button.
// 3. something to show/hide building grid, round towers and round corners sometimes confuses me when building.
// 4. I'm not sure about "target selection function" maybe higher priority for flying units or considering different function for chosing unit... sometimes when first ground units are coming, they take all the hit, but flying units are going on and on and on... it comes to deadly combination tanks+flying tanks :-)
Anyway... huge piece of work done there... 5/5, to motivate and to keep you working on it.
incomplete game if it could be named so...
1. Torque and transmission could not be replaced by only "acceleration" bar...
Suspension is far too soft it behaves more like Zhiguli when loaded. Anyway good physical simulation of truck is quiet hard to program. But once you got the basics it is not so hard to improve...
... nice one, but a bit difficult... needs more workon the conceept... like training villagers or something.... just dont let it die like magicians village defence 4/5
