I love ninja kiwi and I love the bloons franchise but god this was such a letdown. the exp grind to unlocking tower upgrades to use in pvp duels is the worst slog ever. ninjakiwi has made minor attempts to fix the issue in the past but this system is a nightmare to deal with as a new player which only makes the already high barrier to entry worse. the love put into this game's appearance and personality is apparent, which makes the glaring issues in this game feel so much worse. the game is rarely updated with anything meaningful, locked behind the speed of which btd 6 gets a new tower or upgrade, which is close to never. all you have to look forward to while playing are patch notes and balance changes which make the game feel stale. luckily, many of the meta issues that arose during its launch month have since been fixed and the variation in loadouts makes the ranked grind much more fun than it was initially, but i can't in good faith recommend it and it's dwindling player base seems to agree with me.
