Summer Island Battle Tactics

Nice work! The game is looking great!

Not sure if you're looking for feedback but.. I played through the first battle so far, and I have a few suggestions/feedback on the UI/UX:

• The HUD should show MP/HP of SELECTED unit (I would suggest not changing the bottom left HUD when selecting a unit, and instead change the color of the stat that is being affected (eg. turn movement stat yellow as you select a position to show that it is changing).
• It is difficult to understand which units have used up all their actions. It would be nice if this was more clear (color change or animation change) when viewing the battle field (not requiring to highlight each unit).
• It would be nice if the MP was shown on the HUD since it is such a key piece of information.
• It would be nice if things like barrels got destroyed once empty.
• Feels awkward that I can still select units with no actions left. Is there a point to this?
• It would be nice if the game automatically selected the next unit (with remaining actions) after using up actions for the current unit. 
• I know I mentioned it before, but I still think one of the biggest improvements you could make is showing the movement range of the selected unit so that players don't need to "poke around" to figure out what is possible for a given turn. I know it's tough on the NES.

Pretty nice game :)

Unbelievable! I hope you'll release it on a physical NES cartridge! It would be a blast!
