Lot of my friends already reported me a bug which makes spinner orange rooms impassable. The reason for this is that I didn't multiply the spin rates by 'delta'.
As noted by DamianLDF, the possible solution is to change frequency of display to 60Hz.
I think that Vampire Survivors was my main inspiration here, so since the beginning I stayed with idea that the player does only does movement and all attacks are performed automatically. Actually health and contact damage of enemies increases constantly over time. I didn't pay much attension to balancing this whole stuff tbh, so it's funny thing to notice that the number of strikes required later stays the same.
