To me, it was not clear what I had to do in the beginning. I tried clicking on the cannon, but it didn't do nothing, and there was no instruction on how to fix it. In the end, I--for some reason--clicked on the UFO and saw it SPLAT. (eheh)
Gear searching was not convenient, in game, imho: once you understand what you have to do, it is way easier to take out UFOs (since it only takes one click) than dumpster diving (2+ gears vs 1 gear).
For other players that had some problems with the controls:
- clicking on a flying UFO destroys it (meaning, it falls to the ground)
- clicking on broken UFOs lets you retrieve some gears (in-game resources)
- you can also upgrade the cannon with the collapsible menu on the right
- fixing the cannon costs about 10 gears (?), I think
Imho, maybe resources could be collected automatically without player input.
I loved the UFOs.
I liked the idea. The game is a nice proof of concept.
