I had a really enjoyable experience with this demo. It took me over 20 runs and an hour to beat it. I have come close to beating it many times with various weapons but the final run was very lucky due to me managing to have full hp at the boss fight. The boss fight was actually fun trying to figure it's patterns and when to attack. The variety of weapons is also cool as it can both act as an upgrade and adds replayability. Also like how at the end of runs there are permanent rewards that can be used to unlock abilities. I also really like the sounds and sprite work of this game. I had a really fun time beating it.
