I loved this game! All the different combinations of limbs you can get, all the different enemies, randomly generated levels, it's all really fantastic! And I hope you work more on this sometime in the future because this was such a fun game!
The only thing I feel it's missing is a highscore, to show the highest amount of rooms you've cleared in one run, as well as a better way to explain the limb mechanic. It wasn't until I looked at the screenshots I realised you could use the limbs of enemies.
Other than that, fantastic work!
