Yeah. I'm glad it worked out for you on mobile. Since this was a browser based game jam I wanted to make it as accessible as possible. Of course that's easier said than done, like you said the clickable areas are MUCH smaller on a phone. If I play around with the camera angle, I might get something to work (perhaps zoom in more if the game detects you playing on mobile).
It has just come to my attention there was an issue with compiling the android version and it won't install. I can't fix it until after the game jam. Fortunately it works in the browser too. Thanks for your feedback!
