It is true that the game is pretty basic, as most things were rushed through unfortunately. I do want to put more time into it and see where it leads.
Thank you for the bug reports! I did not have time to do much testing with the upgrades so these are really helpful. The BGM slider seems to keep breaking, I’ve had the same issue twice while testing the game out and had to keep fixing it. I fixed it yet again after the jam so hopefully it is working in the next update.
At the start of the jam, I took some time to do proper event signals, as well as dynamic code to make things optimized. But as time went on and I started rushing certain things, I basically dumped a bunch of stuff in global variables and hardcoded a bunch. In the short run it seems fine, but if I’m hoping on a full fledged game, it seems like really bad practice. So I’m still trying to figure out where’s a good balance for this.
Once again, thank you for the kind words and review!
