I've found that some of my favorite games this jam have been the most relaxing. This one is right up there, especially after I worked out what was probably the "optimal" playstyle (i.e. the one that got me to the end). Drop some smooth jazz or some chill flutes on to this, some extra maps, and I would unironically play this to chill out.
I always try to also give input for how to make it better if the dev is interested in doing so. Some people have indicated they didn't like how slow it was. Obviously that was a selling point for me, but I do think that's the strength of developing it more; both preferences can be tended to. Outside of that, it would have been nice if the rubble piles either were mine-able or were a different color from the rocks, so I didn't think they were mine-able.
This game made me happy and there's a lot of games in this jam that can't say that. Well done!
