The best way for me to describe this game is... a difficult but unique game due to how the mechanics work and the reliance on "moving fast" and wall jumping to destroy enemies and whatnot. The fact you need to use your weapon as your main form of getting around (besides wall jumping) can be awkward and difficult to use at first. But once you get the hang of it... things get easier although the difficulty is still there. Perhaps increasing the golem/automaton that you play as movement speed or bullet damage may help with things? Well, I am unsure if I suck at the game or it needs more polish!
Other suggestions I could think of for the near or distant future could be upgrades and things that build around the mechanics of the game? Like bullet penetration? More recoil? Firerate?... Well, I am not the best when giving advice or suggestions on this kind of thing in the end!
