Thanks for playing and the feedback! It's good to hear you liked the bloop and division line, I spent too much time on them but the line was a fun technical challenge so I figured at least I was learning something.
Yeah, it starts out way too slow, I didn't get around to balancing anything and wanted to give enough time understand the chaining but should have made a separate tutorial area. The far right bar is actually the speed meter which increments too slowly (I intended to allow adjusting the speed). The left icons are just representation of your score, a full bar (and level up) makes a gem, 5 gems make a crystal duck.
The time crunch cut all the other enemy types, I actually intended them to attack as well but pivoted to not letting them pass. I plan on working on this some more, thanks for the encouragement!
