Really cool game. Gold'd 3rd level and secret level on mid difficulty, then gold'd the 2nd on hard.
Didn't utilize much manual throwing or jump kicks. Just combo hits, aimed kicks and strafing, as well as strategic gun shots. Hitting and then kicking stunned enemies for quick kill is the best mechanic of the game for sure as without it combat can get stale.
The game definitely shines more with higher difficulty, surprisingly despite throwing in tankier enemies, though not with difficulty spikes as those make me think twice whether I want to replay the whole level. While there's theoretically a decent selection of weapons, the gameplay variety feels stale because of limited selection of enemies and simple arena structure, as well as weapons having miniscule differences in the end (maybe outside of splash damage ones). I liked the third level shotgun on mid difficulty, as I at least had to make a long term decision to save it for the bossfight. Adding that sort of routing elements could make levels more interesting.
