Thank you! I'm glad the upgrades and difficulty felt good, I had to make some last-minute tweaks to get the difficulty right. I'm also not usually a fan of having to repeat areas, so I tried to keep the early stages easy to blaze through. If I had time I'd have added more shortcuts to early levels that you can blast through with later upgrades (like the bombable shrooms) to reduce tedium of having to start from the top.
