Heeey, so in case you see this first: I found an interesting oversight in the main release of 0.5.11. Since it's the main release, I put the details on the main game's page. :}

You can. The walls of the second room aren't coded well for floating jumps, and the slime hazard and wandering spider thing don't function, leaving it just a matter of finding the exit. While this gets you to the town, no areas there function, and the big door at the north of town is a softlock (Probably no warp exit). And since you can't traverse the slime in the first room because it functions and we don't have that power yet, there's no progression to be found elsewise. So mostly safe outside of what corruption of save files might happen later, which I can't verify without time travel. I can't time travel. :{
