Hi,
Well, I didn't expect the game to start as soon as I started it, usually it's a menu scene or some kind of intro, it would be good to have that in the game, maybe in this way it would be possible to tell the player what kind of world it is in front of him.
However, I quickly got oriented and started shooting at everything that moves :). The more I shot mice (or frogs), the more I had the opportunity to pump up my guns, which was quite interesting and fun! Although the first time I got close enough to them, I was even a little scared how fast they ran towards me :D.
Good job with the open world, but the longer I played or maybe moved further, the more the game started to slow down, maybe this is related to the volume of the world that is processed outside the camera (as an option), in this case removing everything outside the camera and maybe with some gap to have a golden mean might help.
It would also be nice to have more contrast with the game information: HP, time, etc., since I only noticed this information at the very end, I think a little contrast would improve the situation.
Regarding the controls, you use the "x" key to replay the game. I'm assuming you're using "e.key" to find the key. In this case, if my OS language is not English, then this code will not work for me. I recommend using "e.code" instead to avoid this issue.
Beautiful and funny animal animation :).
Nice game, congratulations!
