A bigger problem to me is actually that Anger gets a lot more difficult to get upgrades for past 200 (100 for Spite), even with Weird Stone Duck. I'd be happy to see some achievements for getting Weird Stone Duck that increased the effect, although maybe put the actual WSD upgrade option under the Cash menu so people can't get it too early and rush floors? I know that has stopped me from buying Sudden Inhibition even though I have had it available for weeks now.
@aceina while I agree with you that EXP income hits a soft cap around there I should point out that there aren't any upgrades on the 300 Muscularity or 300 Legs achievements, so those are really only worth Sparks. I found this after several days worth of jumping with Auto Abort on with a 5 day max airtime- something that I was in the middle of when the current update added the Sudden Death mechanic, so I have the 1st 5 airtime achievements as well. Not sure how much harder that is now, which is probably why you are struggling in spite of being higher than me (currently working on breaking floor 40 before I Rebirth, it will likely take a few hours).
So I found a problem with platforms. After Leapfrog (which costs 5.0 Tred at level 50) you have to save up 5.5 Quad to unlock Sega Beena. The next 3 you unlock are Nintendo DS for 136.1 Duod, PS Portable for 13.6 Tred, and XBox 360 for 1.4 Quad all at level 5. Pretty sure that based on the costs the Sega Beena should be after those 3.
