I can see how the gameplay might be a bit bad. You can close the "lores" by pressing tab or space bar, i would have made it esc but that would not work with webgl:( I should have just had an ui button that closes it, i only made the cursor become visible for 1 stupid joke:D Also some enemies have weakpoints (for the tanks its the body and rollers its the radiator) but i of course didnt display that anywhere...
