Pretty cool style! Love the trippy background and the MS paint-looking art (I think that style is on the come-up). I found the game really hard, but I think that was intentional to go with the retro-style gameplay.
If I could suggest an improvement it would be a clearer indicator where the thunderbolts are landing on Match 4. Also, a full-screen option would be nice (window is pretty tiny on my 4k display)
