In-Depth Information
By eating insects the player gets stars (up to three per level), which can be converted
into virtual currency to buy game extras.
Stars are earned according to the percentage of insects eaten, where three stars are
granted after eating 100 percent of total number of insects available in the level.
IAP (In-App Purchase)
Additional levels and scenarios can be bought by spending virtual currency earned
by eating insects.
This mechanics is meant to push players towards replaying levels to collect the max-
imum number of insects.
Virtual currency can also be bought by spending real money, so that lazy players can
still get additional contents by paying a small price.
Other contents that could be considered are as follows:
• Additional skins for Grof
• Additional sound fx to customize Grof
• Advanced redo feature to go back any number of moves in a level
We ask you to invent more as an exercise on this section. Think in particular about
contents that allow players to quickly progress in the game. Any ideas?
