What we do know is that the bug is not related to OS/Browser/Flash Version. Replaying the level seems to allow players to get past it, but it may take multiple attempts. Again, it will be fixed within a few hours. Its the middle of the night where the programmer lives :)
Ignore my last comment about chain lightning, we've confirmed thats not the issue, but I still don't know what is. We know it has *something* to do with the little health crates, possibly happens when they land on a mine? I dont know. :(
We believe that the wave 5 bug is related to the health box and the chain lightning upgrade. We're working on it right now, but for the time being, do not use the chain lightning upgrade, let us know if that helps. You may have to restart your game.
To those reporting that wave 5 does not end, can you send me your browser and operating system in a whisper? I'll contact most of you directly! Thanks guys :)
Cool game, I really liked the boss. Wish it had a bit more of a theme and a bit of a break for the high level of tension. It ramps anxiety up pretty high. My brain could use occasional breaks to recover.
This is the easiest to use and most robust version of a sandbox/falling sand game that I have ever played. I really commend you for the effort that was put into it. I love the way so many of the elements interact with each other. Nice work!
