Normal mode: Harder than molten mode, worse rewards, unbalanced, not recommend for beginners (and it was supossed to) Easy mode: Easiest mode, good for begginers, very well balanced (cash wave bonus help alot new players), can be beaten with the starter tower of the game, its just better...
Just keep in mind that the health scaling is different in both games, as towers in tdx usually do around 1.75% more damage than tds towers, because they different games and you should try not to assume that it is harder because the number is higher. Very high quality vid tho good job. P.S. I'm sorry but normal mode is nor harder than fallen, hardcore, pizza party, polluted wastelands, and badlands. It absolutely shouldn't be harder than molten mode, but I think its difficulty is quite often exaggerated because no one plays it to check because the rewards are trash.
