I like the idea, but yeah much has to be changed for it to "get good"
-The music just feels like I'm walking a dog, taking a stroll in the park... Not like I'm fighting with my gang or anything, so it kind of ruins it for me
-The gameplay is extremely basic, and the interaction with your gang members is a bit too limited for my taste... It reminded me of an old flash game (unfortunately forgot it's name) where you have your own ragtag medieval troop; since they all had a name and actual characteristics/stats it felt important and good to go out with them and pwn enemies, here it feels... like not much
-A few bugs (I think) : run and jump, and if you touch a wall or the ground, even though you were like 20 cms above ground, you suddenly get "wasted" (for example run and jump in the wall at the right of the beginnning of level 2, thought it's not the only instance where this happened I remember this one)
-A few other things which are evident but harder to change : the graphics, etc...
All in all though I still found it fun at first, though it's simplicity quickly bored me to be honest.
I appreciate the work behind it though, keep it up
