1. Changed spears into missiles (because the vast majority of people assumed that a spear is a melee weapon). 2. Added a default weapon to the player (i.e. knife). This is a melee weapon which the player can always use when he/she is not holding any other item. 3. Improved VFX and other visual elements of the game. 4. Brightened up the scene's color palette. 5. Reduced the total size of the game from 61MB to 22MB via texture compression and other memory optimization techniques. 6. Added background music. 7. Readjusted various parameters to make in-game interactions more dynamic. 8. Improved the camera movement by means of smoother interpolation. This makes one's gameplay experience far less annoying in case of low frame rate. 9. Fixed the resolution of the game screen to a moderately small number of pixels (in order to prevent performance issues which used to occur on high-res device screens).
