Thank you! :D And I had a couple plays where it took me a while to get towers but not a full round :o were you collecting more than 2 blue energy that whole time?
Ah then it's probably because the blue energy increases the odds of getting towers and stronger units -so if you roll before collecting lots of blue energy then you only get the lowest tier options (mines,cathead and hearts) -I will try to make it easier and more balanced in the next update -thanks for letting me know! :D
