Creation History
User prompt
Add SSR spawns to the guide. ↪💡 Consider importing and using the following plugins: @upit/storage.v1
User prompt
Add enemy SSR bias (MiG-23, Yak-38 and Drones in Ukraine, MiG-23, Su-15, SAMs in Russia, Yak-38 (swarms), drones and Shilkas in Kazakhstan and SAMs, Su-15s, Shilkas and MiG-23s in Belarus)
User prompt
Add a Shilka SPAA enemy (Behaves similarly to a drone, but shoots in bursts (bursts include 5x 3-bullet groups) and rolls vertically)
User prompt
Now make a guide with 2 tips on each enemy, how to use travel and upgrades and Basic maneuvers.
User prompt
Now the Interceptor Split (MiG-23, Su-15, Yak-38) ↪💡 Consider importing and using the following plugins: @upit/storage.v1
User prompt
You can do a Enemy CODEX, as I'm planning the Interceptor Type Split. ↪💡 Consider importing and using the following plugins: @upit/storage.v1
User prompt
Add traveling to different Soviet SSRs.
User prompt
No, the popup for the store is either invisible or does not show.
User prompt
Upgrade store won't show.
User prompt
Add upgrades for the Viggen that you buy with score ↪💡 Consider importing and using the following plugins: @upit/storage.v1
User prompt
Make SAM spawning rarer, it's the main challenge
User prompt
Add powerups
User prompt
Make the viggen shoot bullets at the enemies
User prompt
Clean up shots from interceptor after a bit, should help
User prompt
Game starts lagging significantly after a few dodges
