Hello Deleptual!
We had a clear roadmap at the beggining of the Jam and (as usual) we didn't quite got it as far as we wanted. We planned on progressing through different levels with different hazards (A.k.a different humans .. even with weapons). But at the end we needed to focus on the MVP, If you could turn the camera up you could see that there is other level nearby :'( sadly it didn't make it!
We really appreciate the comments and the improvements, indeed it would be a better start for a new iteration over the game :)
Regarding the upgrades, we went for the basic ones but yeah, we could indeed had this "make your choice" upgrades so players are given a more meaningful choices.
Thank you for your words!!!
