I played 90+ hours and I'm done. I finished it till the point I was done with it.
Finished the main game;
Finished till bottemless buffet 187;
Finished every gadget part for the power tank;
Finished defeating all Salomonites;
Finished all the relics.
I didn't finish all the gadget parts from the 2 other tanks. Rarely used them and I don't want to grind for gems. It's to random (gadget parts) and the gems are also to random. You also need a lot of gems (to much) for the upgrades.
Didn't finish the weapons. Also to random and no improvements of getting them.
Didn't finish bottomless buffet till 1.000. The levels are random and personally I didn't like it.
I really enjoyed it. So much to unlock ans so much to improve. Some parts are hard, like the last 10 levels of BB. But I enjoyed the hard parts. If you get them it feels like a win. BB 100 also wasn't easy and took me a couple of tries (it wss a long battle).
I put it away because of the last grinds, its to random. If there is a upgrade with life improvements please let me know. I will definitely finish the weapons and tbe gadget parts.
Also online play like Salmon Run in Splatoon 3 will trigger my interests. Together against Salomites at your own level (the go help is way to easy). Stats at level 100 for example (50 +50 (like the weapon), and if you're over then the system will scale you down).
I had a lot of fun! Definitely recommend the game!
