When I start the Music Volume is always back at 0, and I need to open the settings to raise it.
The map to select your next mission tile has an issue selecting tiles the further you go from the start. I had to click closer to the start point, often including on the next closest tile, to select the one I wanted.
I cleared 10 sectors, counting the Tutorial. I cleared 2 x 4 section, then went to the corner opposite the start. I like how things started to progress in difficulty. I did the first couple areas with the original droid, then I customized them. I primarily used dual Mining Arms with top Tower Gun. As I reached the later levels I also created one with all three mount points just using the Tower Gun.
Throughout I used a similar solution to what I have done before. I start by getting minerals and fighting off the initial waves, while placing a Root at each of the corners of the starting area, with a Tower at the corner of the area that claims. At later levels I would place a second Tower after collecting enough minerals. Once the base was secured by this, I went around collecting all the minable minerals I could. If some where near a spawn point, I might go into the next phase in that direction sooner. The next phase was to build out at an angle towards a spawn point, just placing Roots out until I got close enough and then placing 2+ Towers. On lower levels I only did 2, and then later came back to add a 3rd. By the end I placed 5 Towers at each. After one was complete I'd move on to the next. For the 30% areas I then needed to claim a bit more land somewhere. If I lost the Droid after all the mining was done, I'd use the combat unit.
The game is feeling much better now that there is difficulty progression and some challenge, even if it is still pretty easy at this point. I still lost some Droids and had to be more careful with my tactics, and felt the combat unit to be useful. I look forward to more customization and growth of the Droids. The game is progressing and feeling good.
