The majority of the effects will be puffs of smoke that will appear when the ground is hit (be it by jumping or an enemy falling back from damage) along with puffs that come from Alfie's gauntlets while she shoots and when the claws lock onto an object.

The player will start out with 3 life hearts. Depending on the enemy the player will either lose half or a whole heart when injured. Hearts can be replenished by finding hidden hearts throughout the game.
