I’m not exactly sure why but these icons look oddly nostalgic to me. Reminds me of the flash games we used to play back in the good ol’ days.
Now I would probably agree with the fact that the icons look quite outdated for 2022 as minimalism is something that is currently in the trend, but that really depends on the project they are being used for.
If you could include the images of your project with the icons being used in it, that would greatly help me better understand their purpose. Otherwise it’s almost like trying to read a book without even opening it.
The objects themselves look great but like what @SMUSH21 said, the effects do not match the items. It’s like having a bucket of water for a weapon, then adding fire on it for effect.
