It could end with after getting all the guns, you touch the gun behind the snake because you can't get back out when you go over the fence

I found it a little bit ago too and I might be going insane but I swear that it shoots faster than the green gun

Edit: We could have an all guns category, basically 100% for this game

The only new time save I can think of is with the bouncy balls in the first room as they can boost you if jumped on the right way.

I'll try to make it run better for my next run, my pc just hates it

I found it by just running over different things to check for weird collision
