Hey you asked me for honest feedback so here it is:
You put a number on the rocks? What does this number does? Oh its the rocks health. All the gaming community is trained to see health as a bar. If you want it to be a number maybe change the color to red.
I read the description to get a feel for the story because people sometimes write it there but it was your CV. While I give you congratulations that you found a game dev job , a dream that many people... well dream, you should have added something relevant to the game also.
You gave us a flash screen with the controls. I assumed that you either control with arrows or awsd. You should have put at least a word like ship above awsd and container? above the arrows. I didn't know you can control the container it took me a while. Yellow card on this.
Can't say I like controlling two things like that even though the ship is auto-attacking.
You were going for an arcade 2d style. While this is a jam you could have selected a more arcady music and sfx.
And now comes the hardest part. You are a game designer by trade. You chose to make something very very very simple compared to the amazing games I played here and believe me I played a lot I am first in karma. If your hadn't put your CV on the description I would say Cool effort mate but from a game designer? Really disappointed.
But you make a living out of this and I don't so who am to criticize...
