Hey there! Its an interesting idea you got there, but I personnaly think the pace of your game is too slow... The levels are bit easy and movement speed of the arm is also a bit slow too. You also could have added more gameplay features, like letting mid-air, or making the player fall if hanged on the ceiling, etc. Apart from these details, is a fun little game you have here! Great job!
Would love if you could check mine out too! Or not, no pressure ;)
