It's an android game, it's my foolishness and lack of time that I uploaded my project as rar file. To play you have to go to source link in which there is android folder which contains the installer apk file.
It was ok, though I didn't see the reason for the differently colored collectibles. You could iterate on the key-down and key-up callbacks though, I can imagine it being done a bit better.
I think I found a bug. In the web version after you click on restart the collectibles get too close together.
Please check it out and I hope you continue making jams :)
