Thanks! Glad you liked it.
And yeah, Techno Lands isn't the best looking map, but I chose it because of the terrain and how I could exploit that in the mission. E.g. you need heavy tanks but they can only go up the middle ramp which is very much anti-tanks.
I'll look into adding a start button. Did the custom sounds for Guardian Wisp work for you, by the way? It seemed to be hit-and-miss for me.

It was a bit fun but I did not play it correctly, nor did the other side get any reinforcements, I just built a nuke.
You need to lock down buildings etc

Thanks for all the feedback so far, this was more of a proof-of-concept sort of map to test the idea out.
I probably won't make any revisions unless there's a game-crushing bug hidden somewhere, and instead I'll take everything I've learnt and all you've said into account on a new mission on a prettier map.
As for those improvements, I'll try and make it clearer as to what the objective is, as well as add some pressure from the AI to stop you just rushing nukes or a DRP.

Anyway, I found out the sound thing works, the image thing works, and that I am somehow competent enough to make a mission. I've also learnt that making the objective and the score source separate is a little bit dumb. Once again, many thanks for all your criticism and feedback.

Any idea why my score does not get submitted?

Should it be played in single player or multiplayer mode? Perhaps some widget responsible for score submission is disabled for me?

Scoring only works in ZKL so if were using another lobby client that particular time that would explain it.
