and proof the Rogue is not unlocked.

The Golem Boss launches himself outside of the map after you stun him, making him unhittable. I also have gotten over 100% Crit Chance but have not got the rogue achievement, I think you have it looking at base Crit Chance and not total Crit Chance, Image for Crit chance proof.

"You" not "I".
I make games as well and slipped.

I could also just make a wall that stops knock backed enemies from going past the fall off point, and add some bounce to it so that they don't stop right in front of the player, would also be very fun to see enemies pinball around the pusher.

you fixed the boss problem, however I have ran into a new one, if a final boss is knocked back so hard that they fall off the pusher from the front they don't come back, I believe they are stuck in the stunned state, which looks like they need to be on the ground to leave.

I don't know specific bosses because they don't show up, but it is commonly First and Final Bosses, with the second Boss usually spawning in but it has also not spawned as well.

The stage does change to the boss stage, Red in the back for 1 and 2, then whole thing for Final.

Thanks for fixing the expanding barrels, I have been playing it some more and found that:

Some Bosses currently don't spawn in at all,

and Mage can defeat himself by launching enemies past the drop zone with Meteors
