I think this was an extremely ambitious given the time frame but you've done incredibly well. The core mechanics are there and feel good even though they could be tightened up a bit (impact affects, shake, etc.) and the existing sounds I think should be changed for something more retro considering the rest of the theme. Please continue to develop this after the jam because it has such high potential!

Thank you so much for the helpful feedback. Core mechanics and feel can definitely be improved further, and I will work on that for the next few weeks. I also agree with the sounds and also music to make it fit into a retro style while still being unique.
Yes, I will be working on this and aim to publish it in 1 - 2 years time. Stay tuned!!
