Thank you very much for playing Onoway!
The jittering on the one-way platforms was due to a temporal fix since players could get stuck on the platforms. I'm currently trying to fix it properly and will patch it as soon as it's fixed.
As for the blocks at the top of the level, that was intentional. Originally, there was going to be a secret level up there. But, due to time constraints, I was unable to do so. I left it as a little thing you can reach if you play with the springs.
Thank you very much for letting me know about the time decrease bug! I was not aware of it and I'll be fixing it now.
I originally planned to make objects which are not affected by time use a different color palette, but I did not get around to doing so. I do agree on letting them keep their color and will be adding that on the next update.
Thank you very much for playing the game and I'm glad you enjoyed this little concept!
