Fire Tactics Prototype

FIRE TACTICS is a game about shepherding the last bastion of humanity  through a fire-torn Earth in the hopefully distant future.  You'll combat flames, giant monster kaiju, and more in turn based battles, your actions all determined by the cards you draft.  That's right, there's turn based tactics on a grid, there are cards, there's deckbuilding, and there's giant mechs punching kaiju into buildings to deal damage!

Prototype Disclaimer:
Currently there is only 1 path through the game. You’ll enter combat encounters, either with normal enemies, minor bosses, or the major boss fight at the end. You’ll position a mech on a 7x7 grid, using energy to both move the mech and play cards. (Moving 1 tile costs 1 energy, although some cards will help you move around for less.) The desired game feel would be one of just eking by while trying to go for powerful combos and abilities, overcoming the minor boss fights and hopefully the final boss as well.

I’m mostly looking for input on how FUN this all feels, if the strategy is engaging, if there are any major design flaws in the way combats play out. This is mostly to test individual encounters and the way cards interact with the grid. I’m open to all and any feedback though, as this is very early and I can pivot (and should), if needed.

This build has has some experimental 'everything but the kitchen sink' features as well (such as cards getting temporary 'Marks', and enemies facing different directions and that meaning something (backstab!!)).
Is it too complex, too simple, want to really badly suggest a feature?? Join my Discord: discord.gg/kxX453xQMX and let me know!!
