Thanks for the feedback!
I'll look into the UI SFX issue - I ran into a couple issues getting the audio channels set up (which is not something I had encountered in my previous games with sound settings), so I wonder if that might have thrown a wrench in the works.
I've had a couple comments about DOOMEI's melee attack - I really wanted to try to tie an animation to it or something, but I'm not the best at animating, so I had to cut it for the time frame . If the team want's to come back and work on it, feedback on a lot of these smaller mechanics is high up on the priority list, for sure!
Difficulty for the game was kinda tough too - as the one who designed the game, I knew that I could just execute all the enemies and make everything really easy due to all the ammo, armor, and HP lying around, but not all players would know that - plus we only implemented a melee tutorial during the grace period, so some players might not have even known about the mechanic (see one of the previous comments). That's another thing I would come back and tweak if we wanted to continue development.
The music is easily one of my favorite parts as well, Grem and Nostalgum did such an amazing job taking the member's songs and incorporating new elements while capturing the feel of the members themselves, and the vibes we wanted for the minigames. Couldn't have asked for a better group to work with!
