We have fixed some bugs! We have added range-field while building towers; added visibility for tower prices; made 3rd and 4th levels easier. We will add more new features (such as new towers, new maps) in the Fortside 3.
dannyboyII, if you lose a level - you can return to map and choose it one more time to win it... if you are in the main menu - so chose LOAD GAME and pick your 3rd level to play.. Sure, if you chose new game - you will have to pass through all levels once again..
