Thanks for the feedback, I'm glad you shared your thoughts!
- Movement system rework will be considered, although I want to keep the focus on drag moving, and have click-to-path as a 'fast move' sort of option. Thanks for reporting the move/aim bug
- I agree that the ammunition and acronyms need more clarification, perhaps in a tooltip or info box
- UI sizes will be improved in the next update, and I'll add a UI portion to the tutorial.
- The new infantry systems aren't in the current published build yet, the next update will have them plus a tutorial!
