Hey. Thanks for playing my game!
I didn't know how to add walls on the edge of the screen back then, so I just added a warning (due to time constraints). Regarding the getting boxed in issue, I am actually going to add another skill to escape such situations( the skill will have other applications, too, of course). Anyways, I'll update the build with new skills and bug fixes within a few days after the pixel jam judgment ends. Thanks again for playing the game and for your valuable feedback.
BTW, I played ZomBen, I loved the concept of having to stick to only certain parts of the level as a living, and other parts as a zombie. It was a fun experience playing that game!
