The additional XP for looting coffins is a great step in the right direction. I think if you buffed the agility xp a bit for looting coffins it might pull the game in balance for sweaty try hards claiming it's OP and normal people like me who don't make tick perfect laps and actually loot. A redistribution from floor 5 xp to maybe 3 and 4 would help a ton too.
i honestly have tried and tried but my ping is terrible on every world for the supulchre, floor 3 with the x2 darts and fire from both sides. i click but no matter what i am delayed and cannot dodge the darts and/or the fire. believe me i have tried for hours. Its dead to me and i give up, the rewards are not worth the aggravation.
