I have a confession to make. I played this game a couple of days ago, and it was just nice. Then, after your feedback of today, I decided to gave another look, just to make sure I wasn't missing anything... And it was amazing. *-*
Long story short, it turns out I was playing to go right, instead of trying to go high. In the second run, in fact, everything acquired sense: the boost, the flying momentum, the fixed camera that was not following the witch's height... Everything was working to make me go up, and I lost it ^^'
Today I was able to reach the end, and I loved the gameplay. The core is solid, easy to learn and slowly increasing in difficulty, in a way that it succeeds in keeping just the right amount of challenge. I also appreciated that the game is not too punishing, allowing for multiple hits before returning to the previous stage. Finally, the audio is pleasant and beautifully mixed. It grows organically through all the stages, and I was stunned. Congratulations for your game, it's a great submission; I kinda feel bad for risking to miss it!
(I already updated the vote, don't worry :P)
