Thank you for you're time and effort. I appreciate it.
You will have to practice the controls a bit but the game is 100% playable. My friend completed all 4 levels in 1 minute and 25 seconds. He did speedrun the game. On the 4th level, there are 2 ways to go about it. 3rd level you have to use a power jump. Every level except the 2nd and 4th one has one power-up. On the 4th level try to use all your power-ups. You can press the sprint and power jump buttons before jumping. I recommend holding them down and then trying to move.
Tell me if you can play more. I will help you play it through.
