(I made the music for this game, plus I am your brother so I will be try to be as unbiased as possible here. :] )
Installation: The game runs fine for me, I was able to bypass a Windows Defender warning as I opened the game and create a desktop shortcut during installation so I didn't have to keep installing it every time. Might be helpful for those having trouble as well.
Art Style: The game looks great for a weekend project. I'd like to see a bit more environmental variety in the overworld map if you continue development. Love the look of the enemies as well. It gives the game a bit more atmosphere that I think is missing from the overworld.
Controls: I had a bit of trouble in the battle menu. I'm used to using left click during battle and it took me a while to find out right clicking was the way to attack. Once I got used to it I was able breeze through, though. It took me a while to figure out that you need to press space to interact with the elephant as well. I suggest adding an options screen or a tutorial so players can view or change their key bindings according to their comfort.
Bugs: Transitioning to a different section of the overworld can sometimes cause a battle to appear, trapping you in an endless loop that forces you to close the game. For anyone who runs into this issue, try searching for a battle just before the exit to reduce your chances of encountering the bug.
Overall, I would like to see you continue this game. (And I would like to continue to make dope beats for it.)
