I am happy that you enjoyed and got interested in the concept.
If you want to see what I want to add / improve you can check the project's page, below where the game is playable, I've added some thoughts on the game :) https://alariann.itch.io/halt-beat
Yes, the missing win condition is too bad, my only resort was to just loop the game. It was a last minute change before I had to stop working on it :). That's not representative of what I was expecting to create, but I've seen too big and you can see the result!
Thank you for your time and your feedback! If you read the game's page, I'd be happy to see what you think of my ideas, and to hear about yours.
