Thank you for the kind review. English is my second language you are right i try my best. A lot of people asked about flashlight battery drains too fast i am going to fix that. And the combine system actually working but not available in the demo. Logic is Item 1 + Item 2 = Item 3. Use is like taking the item in your hand in the inventory screen. Combine is like craft system. The problems you said going to fixed in the next update with Android release. Thank you, good luck.
