I really liked how this simple "match 3" type of game escalated out of control with each new change! :) One thing is that matching the 3 golden tiles isn't as "strategic" as it normally would be, because in normal match 3 games, you can't swap 2 items unless it makes a clear. Here, you can swap 2 items regardless, so the minute 3 golden things were on screen, I just moved the 3 items close to each other so I could match them (instead of actually considering what moves to make).
But overall, this is very solid for a jam entry and it's good as it is ^^ But I would probably make it more challenging and introduce new mechanics faster if this were to get a post-jam rebuild.
