Looks like the Diet Coke version of Streets of Rage 4 to me. Rather just get that.
TTO started development 2014/2015 and was made as sequel/spiritual successor, because none of us thought 4 would ever exist. Obviously, this ended up changing the competition when 4 was announced. I still prefer SOR4, but don't underestimate TTO. The game is basically Streets of Rage 3 with guns, chain comboing (less punishing and less strict compared to SOR4), universal rolls and dashing, and the two out of main three are copies of Axel & Blaze, if they were married and adopted a daughter. You have two attack buttons (while SOR4 always gave you one), a special health draining button with a forward input, and you can juggle enemies with gun fire. Also, your two regular attack buttons has an up input that can launch and juggle enemies, while the downward input is a combo ender, but does twice the damage. You can't wall bounce enemies like in SOR4, but I am not going to hold the game against it. Check out some of these sick moves you can pull off.
