yo I have an idea: hashtags (#), they give you permanent abilities through the run, but they are very rare:
no speed limit: you don’t smash when you go fast enough, to balance it you can’t go past 5k distance
more common stuff: question and exclamation blocks appear more often
everything else is question abilities, except they’re nerfed, spiky cube not included.
evil hashtags (red blocks with an #), rarer than normal hashtag blocks, now they give you permanent debuffs:
less common stuff: question and exclamation blocks appear less often
death: death arrives in 1 minute
less score: ypu get less score, score is 20% less
