Ah lol, that's the default setting for monetization. I never pay attention to it. I never expect money for my games, specially so for Jam games, but thank you for caring anyway :D
The game is as bare bones aimless as it gets, I'd like to break off the sandbox feeling that it has right now. The original Jam's theme was exploration so the only aim/goal is to explore tiles by moving. I agree with you and I'm aiming to give this game better moment to moment gameplay. The current aim is as you said, to chill for 5-10 minutes, enough for a Jam, but not good enough going forward.
I'll try to add some combat, puzzles, smaller levels and stuff like this.
Thank you for your feedback!
