I love the gameplay! It's very addicting to get a high score in, and the simplicity of its mechanics could get you into a state of flow pretty quick... That being said, I think the gameplay would be better enhanced if there was music in the background to get me going. You don't even have to make it yourself, I suggest going to sites like opengameart to search up some upbeat tunes! (just remember to do proper citations as per the uploader's instructions) Some sound effects when the player jumps could also help with the gamefeel. Also I think the game can improve with expanding the clickable area for the blocks or implementing a input buffer system so that players are able to drag more easily the different elements... Good job though, and keep up the good work!
