I played this a lot longer than I expected I would, I realised with the 20% health back using the bat mimic if I dumped all points into attack I could become unstoppable. The scaling with upgrades is really strong so I played until I could 1 hit the boss, such power hahah even with it all stripped back the core is solid and inherently addictive. Also was very nice to not be reset after dying.
The mimic ability could be a little more dynamic if you can only copy 1 ability at a time, meaning you might actually swap what ability you’ve copied mid battle, you know you plan to block for the next couple rounds so you spend a turn to swap from bat to spikes mimic.
Not sure if it’s the only cause for the game stalling but it did it for me if the residual damage from the shield dealt the killing blow for the round. I was able to reproduce it as well and had no problems as long as I used an attack to kill the final enemy.
Really fun stuff had a good time!
