Hey this comment really made my day. That "flow state" you described is really what drew me to hack-n-slash/action centered video games and its something thats harder for me to find these days. I think of games like prince of persia or ninja gaiden where you could just chain combos from one foe to the next.
I think summoning the spear kinda threw some players off. My reasoning was basically "Well, its a seperate sprite anyways and maybe some players would like to move the player sprite around without the spear all the time" - yet I forgot to include anywere that you can also despawn the spear lol.
Thank you so much for your kind words and for taking the time to play the game!
