There are two issues here.
1. Enemies in the same bubble are often unseen, (I found the best strategy is to stay on the outter edge of the bubble and circle around 360 degrees to obliterate the baddies.)
2. If you are looking for action you have to remember which bubble arena's you cleared.
I suggest a bubble radar in one of the upper corners of the screen which would indicate where your enemies are at in the arena. There should be small arrows indicating north south east and west on the outside of the bubble radar. If there are enemies in the adjacent bubble arena's the arrow would turn a light pulsing red.
A gague on the bottom of the screen indicating how many more bubbles collected until your next transformation would also be nice.
I liked it. I would hide my control/repair robots inside of the ship, I would tell them to walk from one side of the ship to the other and cancel when they crossed the ship.
It would be nice to be able to blow up missles or tell units to patrol. I would also like the option of recycling units I am not using and getting my ore back as it seems to be a sparce commodity.
I went counterclockwise and I still have two or so castles to defeat (Im on a lava board in the uper right hand corner and Im pretty much undefeatable. At this point I have little incentive to continue my crew is all maxed out level wise and the enemies don't pose any real threat.
My group composition is a ghost, a t-rex , puppet, frog, a whale , and a foxbat.
Once I use most of my fron rows actions I rotate the back row in and in 2 turns I can clear out everything normally.
Also there seems to be something wrong with the save function because my most recent save seems to not take effect.
Some things that need clearing up early on in the game,
What levels do for your characters.
How levels relate to randomizing
What creatures are available in the randomizing pool of an area
Does one spot on the map have a better chance of randomizing than another, like a conquored castle for instance.
Relationship between the number of a particular beast group and the spells they inhance.
I don't even look at the land bonuses and when I do the explanation isn't intuitive.
Do you get bonuses for not using magic crystals or finishing a battle early? Because if you don't you should.
