There's a lot I have to say about this game so there might be future videos but for now, here's the infinite against the first boss (this also works against certain enemies).

In this game, you can cancel your attacks into the 1+2 special (the dash), hop kick, low kick and turn (away from enemy). So, if you punch twice (1 button X2) then tap the opposite direction then punch twice that way and repeat (turn canceling) on top of an enemy, you get this nice infinite.

If you're not on top of/ inside the enemy, you don't need to punch in the opposite direction, just turn back to the enemy after the turn cancel (1 button X2 → turn) and repeat the initial step, it will still be an infinite.

The first clip in the linked video is another piece of tech which allows you to extend your attack string. (Punch x2 → low kick (down+2) → front kick (1 after the initial two punches)) The timing can be tricky, so only go for it if you're consistent with it. Additionally, you can cancel the front kick into the dash, making this 4 hit string into a 5 hit string.
