Hello!
Wow, thank you for this thorough review, it has great value for us. We pretty much agree on everything you said. Yes, we definitely plan to keep working on the game to polish and adjust it, taking all feedback into consideration. Just curious, the last ability you found was the Roll? There is a possible sequence break that allows finding Roll sooner and this changes the way the map can be explored. The only way to complete 100% the game in less than 11 minutes is by doing it. If you are interested you can see the precise platforming section for the sequence break in this video, around time 3m35s
Cheers
