Okay, I've updated the build and went with increasing the speed of the sharks coming at the player. From Level 15 onwards the speed will increase by 10% with each new level. If it gets too fast too quick I can drop it back down to 5%, but with 10% you should definitely notice the increase in speed. Let me know how it goes.

Whoa... level 22! That's crazy good. Okay, I've now capped the attacking speed in the newest build so it doesn't increase after level 21. Btw, have you tried Cuphead LCD? With your reaction speed I'm sure you would do really well. Currently the best time on the leaderboard for Game A is 2 minutes and 45 seconds.
