I see in the comments that it's your first month of game dev, so I wanted to say congrats on submitting!
Here's my feedback:
- I ran into some issues interacting with items. In the future, I'd recommend some sort of indication to the player so they know that they can interact with an item (such as putting a highlight around it)
- Although I enjoyed spamming the gun, I think it would be cool if you put in a mechanic like "perfect shot" i.e. charging up for an exact amount of time makes the attack more powerful
Those are just a couple things to think about in the future.
Congrats again on your submission, and keep it up! Keep getting better every day and you'll be a pro in no time :)
