itch.io

I understand with the mysterious as thats part of the game.
However I dont think the early levels were easy and doable (especially as webgl can be more sensitive)
You also have to remember you become an expert at the game during testing so what you find easy with hours of practice - others may not.
If you can, its always worth making someone new play the game, (with out telling or helping much), and watch what they do, understand, accomplish etc.
I dont play a lot of pc games so can find controls with mouse and keyboard trciky which doesnt help!
Game designing is hard and the trouble with game jams is there are 100s of other games to test so attention needs to be grabbed quickly or i move on to the next.
I will try and come back and play when I have more time
