Hi r/playmygame,



 I just released v1.0 of my game PCB Defense. I built the whole thing in vanilla JavaScript + HTML5 Canvas over the last few month.



\*\*What it is:\*\*

A tower-defense roguelite set on a printed circuit board. You're the BIOS cannon defending a CPU core from waves of electronic hostiles crawling along the traces. Place turrets on solder pads, upgrade your core, fight bosses every few levels, and stack corruption cards that make every run harder than the last.



\*\*The progression hook:\*\*

Weapons don't cost anything — they unlock by mastery. Reach Level 30 with the BIOS BOLT and the LASER opens up. Reach Level 30 with the LASER and the PLASMA opens up. Then the RAIL. Each weapon has its own separate skill tree save, so equipping a new weapon is a fresh climb, not just a stat swap.



\*\*Features:\*\*

\- 4 weapons with separate skill trees (32 nodes, 5 branches)

\- 25 corruption cards that tier up as you climb

\- Bosses every 3 levels with adaptive HP and phases

\- Runs are \~10–20 minutes

\- Mouse-first controls (left-click place, right-click upgrade, ESC pause)

\- Mobile-friendly HUD, no download, no signup

Feedback welcome — especially on progression pacing and boss difficulty. I'll reply to every comment.
