Finished JackQuest!

Play Store version played, and it was a short but pretty fun game.

Touch controls made it a tad awkward at some points, but nothing unbearable.

Edit - two tips:
In the final boss of the first chapter, the spawn portals are always in the same places, and the boss never drops stalactites on top of the pink crystal to the left, so you can drag the boulder that falls after a while immediately to the left of the left portal, stand on top of the pink crystal and slowly chip the boss’ health away with the bow and arrow while being impervious to damage.
And to start chapter 2, choose to start a new game in the main menu and choose the option to the right. The save for chapter 1 won’t be erased!
