The grappler mechanic works pretty well. I had a hard time aiming it though due to the crosshairs not properly following the cursor. It also took a little too long to charge the gun so it made it somewhat harder to get the falling items. Overall though what you have so far looks good!
Thanks for the feedback! The grappler is not aiming towards mouse cursor (I just forgot to disable it), it is aiming towards the center of the screen (towards the dot)
