Hi. Thanks for trying out my game and your valuable feedback :D
With "alive and deep" do you mean that the game lacks of story or an objective to make the player care to beat the game?
I tried out your prototype and what I enjoyed the most was trying out the leveled up abilities and seeing how different they were to their weaker one. At first I didnt understand that I was supposed to go towards one direction and avoid staying down for too long, but after seeing the bottom row dissapear for 2-3 times i quickly understood what the goal of the game was.
