I made the mistake of trying hard mode, and am on that Veni Vidi Vici rip-off. I'm pretty sure it's the last level, but I've lost all will to complete it.
It's just... ugh. There were so many times where one spike removal, one checkpoint addition or one extra space would've made it a really fun level, but as it is, it's just ridiculous. I guess easy is the much improved version, but it's too late for me to play that.
