the game is hard but really easy to learn. i had only played one game with kbm before this (geometry dash) but ultrakill was actually really easy for me to pick up
the enemies are balanced, and most of the tankier ones have some instakill tech you can learn
i also like how you get rewarded for exploring (e.g. finding alt weapons and lore books) and how messing around with the weapons can lead to you learning insane combos
overall: 10/10 best gift ever
p.s. the jackhammer gives me more dopamine than sex
