Neon red light district or alien cyberpunk dream? Level 3's skybox stacks erotic architecture, fused statuary, glowing circuitry, haze, and layered city planes. Which detail pulls you in first? youtu.be/P5eZCtiZ8cA #IS2 #Shmup #indiegame #ModernRetro #videogames 🌟🎮

The enemies still pop. The holographic chains might pop a little too hard. This Level 3 end-cap pass is about keeping the red light district loud without letting the scenery shout over the fight. youtu.be/o1qsEQKLEoo #IS2 #Shmup #indiegame #ModernRetro #videogames 🌟🎮

Meet Gashira, IS2’s chonky battle giantess. We’re prototyping a miniboss who walks away while turning the floor into lasers. A minute of dodging on the move. Where are you flying first? #IS2 #Shmup #indiegame #ModernRetro #videogames 🌟🎮

Gashira concept art comparing a red-and-black miniboss with a glowing oversized gauntlet against the green-and-white standard enemy. Both are tall armored cybernetic figures carrying extremely long weapons.

Encounter concept showing red-and-black Gashira in two positions, with a bright yellow wall of vertical electrical beams between them. A red arrow points right to indicate movement across the level.

Taking a second to appreciate this one. Final opening shot for Level 3. The NEONIX factory, where her performance mechs are built before they hit the stage. All hand-rendered. Some of our best work yet. Also, beetle butts in the factory are kind of cute. #IS2 #Shmup #ModernRetro #videogames🌟🎮
