Thank you for taking the time to play my game and to leave a comment.
The movement is admittedly very clunky - Due to the way that I've implemented the controls, it checks for the last pressed input and there is a delay for the input. Ironically, it was to prevent too many instances of the robot unintentionally zooming across. I did want the player to have the option of zooming across and be able to turn on short notice, but I wasn't able to get the controls to feel correct.
I'll keep the feedback about the difficulties in mind - initially, I was worried that the lower difficulties were too slow and easy, and that the harder difficulties would still be too easy due to the amount of items that spawn in higher difficulties. Though that's great that you managed to survive every level despite the difficulty - Excellent work!
