Its raw around the edges for sure. When you re-spawn you also respawn in a bugged room as well, but you can see exit and continue.
I don't get that part with balls exploding and lasers shooting. It feels like I am steping on the tile that is not marked red - it should be safe, but I get teleported back into dark room (dead). Tried to tripplejump and stop time to move. But it always looks like red is unsafe and empty space is sometimes safe, sometimes isn't. It didn't trigger in me how it should work. And I was happy to see that puzzle at first :( It probably some visual bugs that I encounter or somesuch.
Its a good start. There is basics of everything, just bugs prevent people from enjoying it :(
