I have released a small update that makes the first level more possible to beat without ending the mission early to collect money. If you would like to give the game another try and let me know what you think it would be highly appreciated!
Tried it again. I had no problem to beat the level now. Maybe it is a bit to easy now. :) Honestly I was not aware that I could end the level early to collect money and muster up my army. I like the concept, but I think it still neads some balancing/streamlining...
