I made the game and I barely ever got to floor 12! So this is great feedback. In the newer versions the faction mechanic is much more pronounced. You get EP for "team kills" and they follow you better. Also the lower levels are balanced better, you can swap armor and stuff.
And right away since that version I got rid of the annoying long zoom out and the spin is a lot faster in the beginning. Coats are always on even numbered levels except the grey coat which it will always give you a new one somewhere on the next level with a grey altar if yours runs out.
To make a more complete game I am working on an end goal related to each faction.
Thanks for playing!
