I think the game has a good base of gameplay. Of course I understand that the three day limit is a harsh deadline to make a game especially as a solo developer now less, but I wish the game was a bit more developed. Also I was trying to figure out how to kill the enemies since there was a hud indicating that I could but I wasn't able to. Maybe the mechanic was scrapped out of time constraints, however I do think the hud have should be removed if that was the case.
The game's difficulty curve is also a bit too extreme due to the fact that the player falls down WAY too quickly. A simple fix that would help with the difficulty would be to place the player higher on the screen so that players have more time to see the enemies on screen and dodge them.
I wish you success in all your future games!
