Dude this was awesome, I already love the game play loop! The actual gameplay is tight and very responsive. I love how crisp your sound design is, those base beats really keep my attention and drive the tension. The visuals are wonderful and fit one another very well, I feel like I am in a version of the old school tron games. Yeah I know, no light cycles but for me I'm locked in each round. Numbers go up! Loads of that here and everything I saw does seem to matter but for me personally it's one of those oh that's cool kind of features.
If I had any complaint, it's that I personally would love a story with the game. Does it need much of one? No, not at all, but you have built something awesome here and I want an excuse to spend more time here. Even just small snippet messages about what's going on when I hit a level or certain amount of sessions would be golden to me.
I would legit play longer just to know more about it, for me personally, if I wasn't designing games as well I would spend way more time here. However, your web version of the game made me realize I really need to tune up some things in my own project because, wow I am humbled by what you've pulled off here. If there are story elements already and I missed them because I ended my play session too soon, no worries. I know I'll be back to check this out again.
Keep up the great work!
