Weapons and combat
- Four weapons ship in the engine - Pulse Blaster, Blast Shotgun, Photon Sniper, and Plasma Rail - each with level-based stats for shot count, fire rate, spread, damage, pierce, and velocity.
- Your current weapon level and speed level show on the HUD during a run, next to a dash indicator that reads Ready or shows a cooldown bar.
- A mute button toggles the procedural sound effects and background music without leaving the arena.
Spending Energy in the shop
Energy earned during a run is banked for permanent upgrades that carry across future runs. The shop spends it on Tactical Bomb, Orbiter Escort, Weapon Boost, Quantum Drive, Nano Armor, Time Dilate, Orbiter Expand, Cryo Core, and Recoil Damper - each with a maximum level and a cost that rises as you invest.
Frequently Asked Questions
What does Neon Energy Arena do?
It is a neon arena roguelite in the browser: fight geometric enemies with four switchable weapons, dash and bomb for survival, then spend earned Energy on permanent shop upgrades between runs.
Does it work on a phone?
The page and game load on a phone, but aiming and shooting need a pointer (mouse or trackpad). There is no dedicated touch HUD, so a desktop is the practical way to play.
Is anything saved in my browser?

How big is the download?
About ~90 KB of HTML, JS, CSS, and favicon after you press Play. The browser caches it for later visits on the same device.
How do I control the ship?
WASD moves, mouse aims, LMB shoots, F cycles weapons (Pulse Blaster, Blast Shotgun, Photon Sniper, Plasma Rail), Shift dashes, Space drops a bomb, and Esc pauses.
