Thank you for liking my game!!
I know.. the "Lil' Boost" is too spammable, you see, I wasn't able to add many of my ideas (surprising) so at the very last 30 minutes, I added a Lil' Boost button and shipped it, I do want to improve on my game in the future!
Also, yes I should consider adding more visual effects and UI which help the player know how to play the game
