Thank you for your long and detailed answer! I'm glad you like it!
Unfortunately, I had not had enough time to create as many levels and mechanics as I originally wanted. That's why there were only 9 levels (the level with the first blue platform is 7). If I find time in the future then I would like to make the most different levels with your asset pack! I thought of a desert level, snow level and much more!
1. Yes! in any case I will add a restart button. I have often received this advice and I wonder why I have not thought of it myself. :D
2. I don't know exactly what you mean by that. do you think you should be able to control the game completely with the keyboard instead of having to rely on the mouse? I was going to rework the controls anyway. Especially to add gamepad support.
3. to be honest i didn't know this site. Is it like itch.io?
