Fun but short-lived
I thought the game was fun, but it got a bit tiresome after a while. I took the advice and kept playing until after wave 10, but even with the introduction of the tanks I was finding the gameplay a bit tedious. The sounds were also quite grating after a while; particularly the screams of the soldiers. A bit of diversity there wouldn't go amiss. However, it was quite a fun and original game, with excellent backgroud scenery to each wave. Well done!
