hmm..... which room? i found myself in a similar predicament once
gosh, hard to remember now. It was in the second stage? I believe, just before trying to destroy the fuel storage to advance to the next level. I had lead the soldier at the lowest level to the next screen, and accidentally died to it, so when I respawned at the start of the screen, the enemy was there and instantly killed me.
Maybe having a window of invincibility on spawn? I mean, it isn't the biggest issue, especially considering how short the game is.
