Thank you so much for playing the game!! It's not that difficult! Great map you've created.
And now I see in the map that I missed a room, aargh, do i really have to replay it :D
I did try to play it as intended, but I don't enjoy the idea of geting completely stuck just because of firing too much bullets - a way to recharge bullets (a bullet station?) or if the enemies would stay dead, would perhaps/probably make the game much more enjoyable for me game-wise.
But that's just me, and it still was very fun!
