i cannot download it weird i just press the download button and it just doesnt do anything, even with the itch io alternate download mode
Not sure what's going on there. I tried it too just now and had the same problem, but then I tried again and it worked. Maybe some temporary hiccup somewhere.
Anyways, as mentioned, you can always download it directly from http://labbed.net/software/labchirp/
Have fun!
