Thank you so much for your feedback! So I gathered a few suggestions of you guys and made some minor fixes and adjustments, here's the details :)

[UPDATED KEY BINDINGS]

When you complete or fail a level, instead of pressing [←] to retry or [↑][→][↓] to go back to menu, it's been replaced with [SPACE] and [ENTER] respectively, to avoid pressing them by mistake.

[MINOR PATCHES]

• When pressed correctly in succession, particles spawned didn't spawn again until it completes a cycle, this has been fixed and it will always spawn immediately instead.
• Rotate panels now have different colors to distinguish between clockwise and counter-clockwise.
• Oof typos lol. Got'em.

Thanks for your feedback, y'all rocks!
