Hello PseudoPStupid, thanks for playing! I saw you laugh a number of times and really enjoyed that you understood the "Killing Joke" achievement reference.
I'm sorry for the difficulty. At times it really felt painful as a dev to see you struggle so hard in the first two levels. And sometimes you were so close. You had an exploding box lined up with loads of enemies around it, then you exclaimed that you like the laser only to not fire and then expend ammo and lose health. You were close to figuring out how the rats move (they jump in the direction that they are facing) and then you waived it off again. :)
Sorry for the confusion in the beginning. The game is play in browser and you downloaded the manual. The full screen setting works well in the browser though. Regarding distribution: It's in the browser as that's the least hassle for everyone to play. There is also an Android build on google play.
It is very clear to me that 1. The room reveal has to happen faster and line of sight not be blocked by enemies. (This will mitigate the rushing into rooms effect. This is so deadly.) 2. There have to be some doorways that are wider than one space in order to avoid so much fighting in the doorways.
Glad that you enjoyed it, thanks again for playing!
