Thanks for your short review, all this feedback is very useful! I have already made some updates based on some issues, but others will take a bit more time.

I tried to make the intro sequence without text but it's clear that I made it too vague. I will think more on how to better explain the energy use of the factions which becomes more relevant as you play.

I have moved the building health so it doesn't overlay the unit health.

I have been weighing up whether to include a tutorial or just let the player figure things out as I didn't want to be restrictive, but I think a good balance would be to add tutorial tips that aren't required to be followed.

The units reverting their moves is from an option that allows the player to confirm their moves. If this option is not enabled then the use will confirm automatically. Either explaining this upfront or giving the player an option choice at the start would be a good idea.

Killing an enemy with two units is a bug that I am aware of that is queuing the attacks before the death. The first unit should kill the enemy and the second one should either not be able to attack, or should attack the building underneath.

The AI in the first map deliberately doesn't do much to not overwhelm the player, and for other maps I am still improving the AI strategies.

I have removed "Charge weapon" from the results until it becomes relevant.

You are playing as part of the Terra Federation and reporting to Jovian is a betrayal of your faction and supporting Jovian Republic for better rewards. I was trying to explain this without much text but I will need to add some more explanation in some way. This also ties into the energy of the factions which is revealed as you play but perhaps I should make it more clear from the start what it means.

The unit stats are explained in the battle info window as I didn't want to overwhelm the screen with too much text. Unit advantages are shown when selecting relevant units, but this isn't clear with the starting units. This is also similar to issue with the tutorial that I didn't want force the player to view it if they didn't want to.
