Really nice game!
Don't know why, but this just screams speedrun potential to me, if you want to continue working on it.
The controls feel very nice and responsive and the graphics look really neat, good job on those!
The globe opening and closing seems like it would be cool if you had to only pick up some things but avoid others (like maybe fish?), but as it is right now it doesn't seem to add much. Also, as others pointed out, not being able to close the upgrade menu can force you to buy upgrades you don't want, or even hard-lock you.
Overall, I'd say it gets a bit repetitive after a little bit, but it's a really solid base for a game if you wish to continue it. Nice work!
