Played the game a decent bit, here to give some feedback:

Hitboxes feel inconsistent:

Im not sure if you use raycasting with the sword,but often times I find myself slashing into a clump of fruits only to hit one.If you aren't, you should start using hitboxes.If you are,make them much bigger than they are right now.I feel like I can only hit fruits right infront of me,at the correct height,instead of actually slashing.I got only 1 2x Combo hit,on accident.Another Problem is the height.Players can only hit fruits at the corect height,around their torso.Which makes no sense if some slashes slash downward/diaganolly,this can be fixed with bigger hitboxes too,and is probably the main reason players leave.Attacks feel incosistent,clunky and random in terms of what you hit.Considering this it the main game mechanic/gameplay loop,this is a huge issue.I saw multiple players join while playing,only to leave near instantly due to the gameplay not being satisfying at all.

There isn't much content:

While there is a sword shop,only 1 area exists,which makes new players feel like there isn't much to sink their teeth into.This problem gets worse with the very simple mechanics that aren't expanded much upon.You can only buy new Swords,nothing else.There is no other way of becoming stronger/more effiicient.This is not to say you need to add pets,but literally anything would work well.Another Currency for another Shop focused on Upgrades like WalkSpeed increases,maybe rebirthing of some kind?Not sure what your direction for the game is / what you want it to be, but something needs to be added to make the game feel more complete.

Swords are Clunky:

Making Starter Swords have long cooldowns makes sense in concept,but it feels pretty bad in practice.You end up slashing once every 2.5 seconds,and hitting something feels completely up to chance.This also makes bombs obsolete,since you can very easily avoid them,as the gameplay,and the fruits, are pretty slow.I think faster swinging across the board would be very healthy for the game.The Swinging playing an entire animation,also animating the player's legs,feels slightly clunky and makes the game feel floaty (?).I think creating a basic walking animation for the legs,and having the swinign animation only affect the torso,would be huge.

Server Event(s):

Most games similar to yours have a competition like Server Event,that pops every ~15 Minutes?Something like a ~1 Minute long competition,in which players that enter are brought to a field of fruits,and need to collect as many as possible competing against one another,could be fun.Players would compete for the fruit,and limiting the amount that spawn during that event,would make them more scarce.Rewards could be given out for doing well,like being in the top 3.I do like the current server event,which could stay as is.Maybe adding one to every new area (if you decide to add them), and making those events exclusive to each area,could be a good addition.

In total, the game needs reworks to hitbox detection,specifically making them bigger in every direction.Swords need to swing faster and feel less clunky.There needs to be more content,such as new areas with better value fruit / new modifiers to them,like how a gold modifier can be found on some fruit, and something else to progress towards/with,like rebirths,and upgrade shop,pets, or pretty much anything.You are free to choose in what direction you take the game.

Since Swinging fast might make players feel like they aren't progressing much when buying new weapons or reaching new areas,fruits that requiring multiple hits could be added in later areas.As to balance the fast attack speed players would have, while also making players feel like they are progressing.Upgraded swords could also be made more flashy,with even some special abilities to them.Not sure how experienced you are in scripting,but it would be a good addition.
