i like how we gain units but it whould be better if we could buy upgraded versions if we wanted to so people have a choice in what they want (the upgraded type whould have seperate upgrades)
and the heroes should be better in the later levels, which could be fixed with being able to buy the next "level" that has several general upgrades and the upgrades themselves whould just be a way to focus on damage or health
within 1 minute my browser froze from awsome overload (or just proccesing too much but thats just the "prop3r" phrase), within 10 seconds the doll got hurt so much it was "sleeping"
