Oh hey, a fellow match-3 submission! The polish of this game is incredible and I really like the concept. I love combining match-3 mechanics with other gameplay, and this might be the most interesting implementation of that general idea I've seen. As others have pointed out, it's currently not very playable due to the lack of movement, but I think there's a fantastic (and sellable) game here.
Maybe you could just separate movement from the rest of the mechanics. That could be anywhere on the scale from "the player can move freely at any time" to "the player can only move forwards by X steps per turn", but that seems like it might be easier than rebalancing the grid to provide you with enough movement tiles (without losing the flexibility among your combat options).
Anyway, despite the movement issue, this is a fantastic game and absolutely incredible work for a 48 hour jam. I hope you polish this up a bit after the jam and release it properly!
