thank you for the feedback. Especially the tentacles, I was just trying to make things look cool, but then realized the immediate reaction is that these seem harmful.
Yeah I did do complete grid based stuff at first but it didn't feel as good, so my compromise was the bomb.
clearly defined exits would probably be a bit more fair. My only somewhat fix was that if the exit is close to blocks it does blow them up, but this doesn't always result in you having a clear path.
