what level are you on? Do you have enough energy?
the first level i loose all my energy and was not putting the zombie and then after losing my energy again and again, It worked once to never (I'm playing on the phone and in the itch.io).
Thanks for the report, i'am looking into it. You can play the app from the playstore meanwhile.
Fixed, in the webgl version there was an error, it was sending multiple taps at the same time.
Nice
