Very tricky little game. Challenging but definitely enjoyable! Has some satisfying game feel and player feedback.
If there were a couple things I'd like added, it would be collectables, and the option to adjust the speed of the game. Collectables would add an extra layer of challenge and also help guide the player in certain directions. The ability to slow the game's pace down would also benefit players that can not handle the game's fast pace and difficulty. Game difficulty is like a spice; not everyone can handle it and some love it.
Great game :-D
