Very good game. Good graphics, good animations, and fun. Really like it.
A suggestion... I understand that it's necessary to have a predefined pace for creating the enemies, but if the user is fast and clears the screenof enemies, could be ok to accelerate the creation of the following ones to avoid empty seconds of waiting.
Anyway, it is a very good job. Congratulations!!
By the way, the game in the dsk file hangs the first time you click fire, but the one in the CDT works well.
