Thank you so much for playing our game, and for completing it. Thanks for the telling us about removing the rock pile at the end without the dynamite. We treat the rock pile as a barrel and yes, you can indeed remove it with the crowbar we just found! Doh!!!
Sorry about the load/save problem with the enemies still blocking the square. It was a bug we introduced at the end of the jam when trying to get enemies to disappear once you'd killed them, and we missed a crucial line of code.
We'll definitely work on making combat more engaging post-jam.
Feel free to check out our devlog if you want to see more in depth how we did it all:
