Pretty neat! I liked the style and the game loop =). Does matching 4 or more in a row give any bonus? I didn't notice any, it would have been good to feel rewarded for setting up a nice combo =). Pacing seemed a little slow, I played quite a while and only made it as far as unlocking 2-2. I seem to lose pretty often on 2-1, and that's the level I need to play to get stone, so get stuck in a bit of a loop.
Like the aesthetics and audio and super quick load times =). Nice job!
Thanks for the feedback! Matching 4 or more only provides a bit more resources (linearly), I had a nice-to-have todo to make 4+ matches spawn a 'super tile' that would provide bonus resources if matched, but it never bubbled up in the queue before the deadline.
Both enemy balancing and upgrade cost balancing were pretty rough to get just right in the short time of play testing the final values towards the end, there were a few last minutes tweaks to try to ease the difficulty a bit, but I also wanted to avoid making it too easy breezy.
