This is not @tomicool's engine, this is PSE (Peak Sonic Engine) which I (@Enigmatic21) created. You can see the official project here: https://scratch.mit.edu/projects/1180997679/ @tomicool made the level though, and I have to say it makes a brilliant testing ground for spotting physics and collision issues! @tomicool's engine https://scratch.mit.edu/projects/74711180/ The primary difference between our engines? Mine is engineered for SPEED. Seriously, try them both, the difference is kind of shocking. Jump/Walljump - z key Drop Dash - press z key again (while jumping) & hold it Move - arrow keys Crouch/roll - down arrow Look up/down - hold up/down arrows Spindash - double tap down arrow Stomp - double tap down arrow midair Toggle day/night - N key Like many of you, @tomicool's Sonic Engine was my first impression of what was possible with Scratch. At the time, I remember thinking I would never come close to the level of technical understanding required to build a project like that. Kind of unreal how I keep proving that notion wrong. I'm putting his level in my engine because his design really is magical, it redefines how you look at programming, makes you go, "wait--a single person can make this? On Scratch?!" Is mine a better engine? Perchance. But mainly, it's my best attempt to recapture the wonder I felt after clicking his project's green flag for the first time.
