I especially liked the second half of this, where the d20 effects started occurring, as well as the boss fight. Glad you checkpointed me before the boss too, because it would have been frustrating to do the whole climb all over again. I think for normal enemies the randomness of the die feels less interesting, but it works on the boss, especially when paired with the x2 and x1/2 effects, where you really feel the difference in attack power.

Thanks for the feedback! Originally the entire game was going to have the d20 effects but that felt too chaotic so we added it into the end as just a gauntlet before the final boss. I'm glad that checkpoint worked properly, it was a very late addition as I was worried the game would be super frustrating without it
