First and foremost the .exe download it’s an installer, I don’t know if the zip is any different, but I’m not a fan of having to install anything in my computer just like that.
Now, about the actual game, it’s fun, the art is nice, the animations are great, jumping is fun which makes platforming enjoyable. My only but would be that with high jumps the camera naturally goes too high up so you can’t see where you’ll land, which is an issue for a platformer, but overall very fun game.
