It has potential.
Music is good, using text at the bottom was interesting although well-used, idea behind the game also very cliched and used greatly before how the gameplay was well implemented.
The biggest down fall I would say would be the lack of checkpoints as I eventually got to 7345 and my third attempt, not particularly good however I can not be bothered to redo all that again and therefore, for Just Avoid It 2 I recommend checkpoints every 5000 score.
Overall, a good game and for the few floors it would be scoring a much higher rating.
Well Done and I hope to see JAI2 in the future.
