Innoquous 5 has been updated to make some of the late-game levels actually possible to complete in game modes beyond Standard. Others are fairer - for example, Hop 3 only needs to be "completed" twice in Conditional, rather than three times.
There are also a couple of minor fixes, such as the controls being a bit iffy in levels where the condition reverses left and right inputs, and the bunny being readded to a level where it didn't appear in Bunny Hunt - no bunny left un-captured.
