Round 140 With Only Submarines in Impoppable (Minimal Support)

Описание: Bloons TD 6 Impoppable challenge using only Submarines, reaching Round 140 with minimal support.
This BTD6 run focuses on submarine-only strategy, late game survival, and careful placement decisions.

The run started as a simple question:
How far can I push Impoppable using almost only submarines?

No meta spam, no fancy setups — just subs, minimal support, and careful timing.
The run reached Round 140.
With better positioning and fewer small mistakes, I’m confident it could have gone even further.

But this video isn’t really about Round 140.
While playing, I kept thinking about something completely different — trail running.
The way endurance works.
How pushing too hard, too early, usually costs you later.
And how patience often gets you further than raw power.

That same mindset shaped this run.
When to push.
When to hold.
And when not to force progress just because you can.

If you’re here only for the gameplay, enjoy the challenge.
If you’re here for the story, listen closely — it’s there between the rounds.
