The punching mechanic felt juuuuust right. Would have loved a shop so that I could further upgrade my fighter along with the pickups. I pity the poor soul who brings a shield to a thunder punch fight.
I too pity those shield suckers! I'd planned on adding power ups, like time-freeze, shield smash and speed boosts etc. but didn't get time in the end to implement properly. Definitely something to consider if I want to flesh the game out a bit more in future though!
