I enjoy puzzles like this so I was having run working out whic rocks to move to in order to line up my escape. I'm not sure whether i like being able to throw more stuff while travelling or not. Aesthetically having jimothy be greay on the dark background was not the best choice as it was often hard to see him, especially when there are lots of rocks around. Also it would be a great quality of life fearure to be able to press R or something to restart the level so that you didn't have to sit through dumping all t he trash once you realise you messed up.
Overall well done, the game could use some tweaks but its a solid concept.
