I just want to say from a player who's play Open Hexagon for 3 years and has thoroughly pushed to exceed limits and only downloaded this game 2 days ago, I present to you Mr. dev Level 1's Hard Mode completely destroyed with 1393.86 Seconds, can definitely push farther if I wanted to. ;)
I was successful in beating Level 2's Hard Mode, albeit the transitions are getting me more as well as the new camera trick, level 4 with the alt barrage (The pattern that has half walls half gaps 1-1) on Octagon is very tricky and to me personally it's awkward, but maybe it's due to me having a lot of trouble with the current gimmicks of the level, but I'll hopefully do more with Level 2 and Level 4 when I can.
