Yeah Pie mode felt extremelly balanced overall, but I am a little suspicious to say that x)
And it actually made energy management very interesting, since batteries only ever recovered one point of health every damage I took felt way more impactfull and made me have to actually adapt and improvise my gameplay around the amount of energy I had.
IWBTG stand for "I wanna be the guy", wich is a series of "kaizo" styled games (As in, like kaizo mario, if you know what I mean)
The original IWBTG games are more "haha get trolled stewpid" than actual platforming challenges tho, but the fangames, wich is what I consider the actual bulk of the series, focus way more on the ridiculous precise platforming instead, it's very fun.
You can get I Wanna Maker for free on Steam, it has a story mode with lots of very cool level design, and as the name suggests you can also play levels made by other players, I totally reccomend it as an introduction to these kinds of games since it's also fairly tame compared to some other ones
