Positive ✅
🎮 Had all the core elements, which is decent for 3 days’ work
🎯 Custom reticle makes aiming feel much nicer
🛠️ Upgrade system is a nice feature that adds depth
Suggestions 🛠️
🚀 A projectile speed upgrade would be cool for later waves
🖥️ Being able to go fullscreen would be a nice enhancement
🎨 Contrast on the upgrade buttons is too low — a bit hard to read

Really nice submission!
