I got this one for judging so here are my thoughts:
Interesting start to the game and idea. Got a good hook to get me started. Not sure how I feel about being dumped into a battle though with no time to learn anything about the game or skills, especially with as many skills as you have. At least the first battle is easy enough I could fumble through it as I learned the set ups.
Wait, where is my menu outside of battle? Default keys for bringing up the menu do nothing. I assume there is a menu from the screenshots, so you really need to tell the player what buttons you are using for it if you are going to change it on people. Looking at that pic it looks like you hid it on the far side, but I had no way of knowing that as we get these to judge without the itch pages too. Never assume the player has seen the screenshots and always show them if you change the systems from default.
Since I never got the menu to actually pull up in my entire time playing this I also had no way to heal at all between battles. This made battles a little more difficult than I feel they should have been.
Speaking of battles, due to the random TP you get at start I had some battles I couldn't do anything on turn one as every skill but attack needed more TP than I got. Maybe investigate scripting it so that you can start with more? Though I do wonder if skills really need HP MP and TP costs all at once? Feels a little overboard and could be simplified a little.
Menu and healing issues aside I do feel you have a solid entry though. A tutorial to explain the changes would help though. I do hope you expand on this though once the contest is over.
