Challenge Mode (CookieVSCookie's Conception)

Challenge Mode is a new mode which is unlocked after beating hard difficulty five times

All normal stats are same as hard mode, except for round #, which is now 90

New Mechanics
Health Scaling is a new mechanic in challenge mode where every 3,000$ spent increases boss/blimp health by 4 hits.

Aditionally, every 10,000$ spent adds another ceramic bloon to M.O.A.B.s

* Every 30,000$ spent adds another regrow camo ceramic to D.D.T.s*

Every 5,000$ adds another zebra bloon to B.L.I.M.P.

Every super monkey you have adds an additional 2 HP to blimps/bosses, and 1 adittional extra hit to multi-hit for a layer (eg: ceramic bloon).

Every ToTmG you have adds an additional 10 HP to blimps/bosses, an additonal Zebra bloon as a child to all bosses/blimps and +5 hp for ceramic type bloons

In freeplay mode, all cash buff effects are doubled & all regular bloons make you lose 50% more lives (or $ if applied)
