I can say it was a success, it got me playing until the end! If I had to complain about something, the leveling up felt a bit disruptive, maybe reduce the frequency and increase the upgrades "power". And the level up music stopped working at some point. Overall the game was good and it accomplishes the goal of being addictive. This isn't related to the game, but I'm sad I missed the jam! I'm from Spain and I would have loved participating in it.
