Ryu is not amazing in this game but i think he is solid enough. he is kind of slow but you have fireballs and shoryuken to keep people out. Cr MK is your best range normal and you want to try to cancel into drive rush any time you hit that, even on block, because it will put you close to them for a very strong mixup. if it hits, you can confirm into HP xx Donkey Kick > Super. you can also just raw drive rush into cr MK to spend less bars and still get a very + mixup on them (also hits low from very far away). once they get used to it, change to overhead.
can be a lot to balance storing the denjin + having solid neutral, when to spend it as well so you dont waste it. it is a very powerful move but very hard to use. i see a lot of players neglecting it entirely. can lead to massive damage in corner though if you happen to get one (can be a hard scenario to achieve though)
Not sure if this is common knowledge but if can figure out when people are going for throws on your wakeups, the best option is to back dash + punish their whiff. back dashes are throw invincible so its the best way to escape a regular throw.
