I got to the bubble end part (it looked like it was the ending) in about an hour and a half, but I fell all the way to the water floor... 2 times... then I quit. The jumps felt very satisfying after learning and succeeding on the platforming. Overall nice game, even though these usually aren't my style. But seriously, keep the odd level design like that, not being able to know where to go, and discovering the path is one of the best parts. I only recommend adding controller support if possible.
Thank you for your comment! The bubbles are very hard part and in full game are very hit at the top. Although while testing it I got king of good at it and it feels like not to hard enough. So these insights from someone else are very helpful.
I'll try to add controller later. That's in todo list.
I'm gonna release updated demo version with multiplayer to steam soon. Fell free to wishlist it.
Thank you very much!
