Egyptians vs Vikings

Egyptians vs Vikings is an isometric Tower Defense game made in a classroom by 4 people, the game has been made from Clickteam fusion and some of the bugs that are found in the game could not be solved due to not enough experience with the program. If anyone does know how to solve these issue, it would be greatly appreciated.

p.s. we have only made one level, sorry if you were expecting a campaign of some sorts.
