Greetings everyone!
I've released several more updates over the last few days. The updates included changes to some of the missions and challenges to make them more difficult. I did several bug fixes. I changed the amount of money in Sandbox mode to 900,000, so you should be able to build an army as large as your computer can handle.
There were some bugs with wave mode, for some people killing wave 2 wouldn't trigger the next wave/victory condition. I believe I have found and fixed the cause of this issue. If you are still having issues with wave mode please report it in the comments. I will try to figure it out.
I'm getting ready to move on to implementing more features to the game. I am currently in the process of implementing a new unit, I have a few ideas such as a rocket soldier, grenadier, mortar, Gatling gun, officer, and drummer. If you have some ideas for more units, comment them below. I want the units to stay in the colonial age, so I don't think I will be implementing anything too modern/sci-fi.
Cannons still seem to be OP in large numbers, so some of the units will have a bonus against cannons. Once I add a few more units, I can expand the missions and challenges a bit more.
Thank you all for your support!
