Thanks a lot about the nice and in-depth feedback! We are already considering releasing a mobile version (although coming up with levels might be an issue - the later levels here already took several hours to develop).
It would also indeed have been a sweet submission for the GMTKjam, a shame I had work then.
Thanks for mentioning technical issues too. The tag is something we didn't catch yet, we'll try to remove it. We can't seem to reproduce the restart issue though, do you have any steps to get it to happen?
If you have any other feedback, feel free to let us know! :)
