Thanks for checking out Diamond Dash!
This is a project I've been working on and polishing for quite some time, and I'm happy to say it's finally released! If you love platformers, puzzles, and fast-paced challenges - have a look and let me know what you think.
There are 160 levels, 25 of which are available in the demo. If you want more information, here's the game page for some screenshots and details:
Hope you have fun! :)
