I played this game many years ago, the tank 1 soundtrack is still on my head's music. When i play it, you can find me vibing to every track the game has to offer.
At 2020 i even attempted to speedrun the game, with horrible results, so i never recorded myself. More people should try this game, it is like Plants vs Zombies' hidden prequel.
Post game modes are similar, but are different enough to be recallable. Having a nice virtual tank was a goal i had, up to 20 fishes named after footballers, and the possibility of having the tank as screensaver, and fishes producting shells while i was asleep. how times :)
