I LOVE this concept and the execution of it was great. The intro really caught me off guard and it honestly made me care about the monkey a lot more than I thought I would, completely wordlessly. On top of that, it's just a really fun game and the pixelated old-school graphics are great! You did an incredible job on this game.
One funny bug I found was that you can shoot through some walls hah, but it isn't too game-breaking as it generally isn't very helpful in most scenarios. Having the environment block projectiles was a great touch too, and it made combat encounters a lot more fluid and nice since I had things to hide behind if I was getting overwhelmed and needed a second to catch my barrings!
