First things first, sorry for the super long comment
Just beat the game and I have a couple things to go over.
I dig the visuals (no pun intended), the idea is great. I found a couple things that could be easily fixed:
The non minable blocks, even if specified that some can not be pushed on the "how to play", could have something to tell the pushables and non pushables, like a slightly darker tone for the non pushables so the player can identify those right away and not have to reset the level because it trapped itself, I'm playing on controller, not sure if support was intended, but it has no "reset level" button, needing to use the R on keyboard instead (so not that big of a deal there, just a QoL thing) and only the joystick can be used to move, d-pad is not working. The movement is nice but on corners some times it can be a little slippery, on flat surfaces seems to not have that problem.
for a small 7 day solo game with all original assets is really nice, simple, but still nice.
