I like this game! Simple and challenging. The art is clean with good high contrast and the gameplay is easy to understand, but yet difficult. I found myself trying it more than a few times.
I do wish there was some sort of background music or ambient sound during the level. Also another control input, like a PC controller or click and drag to follow the cursor. Which, if you did the follow the cursor, it would lend itself well to mobile... which I could see this game doing well on.
The highest score I was able to get was 1394... I was able to get two trails on either side of all three hexagons. Then I just moved up and down... at one point the game was spawning so many enemies I thought I saw them destroying each other.... The game did start to lag at that point because of all the particles and enemies on screen.... but eventually I did die.
Great game.... very solid submission
