This is a really simple game that is inspired by the famous Pokemon franchise, whose two main medals are pretty easy to get: catch your first Pokemon and catch a Beedrill or a Butterfree. The last medal is more difficult to get because it's very random both the chance to get the shiny and the chance to get it after first tries (keep in mind that 1 in 8192 is a shiny Pokemon). I initially got a shiny after around 1000 tries, here the proof:

But I didn't initially get the medal, I don't know if it was because the game disconnected after some time, so I decided to replay it and after 20 tries I got my shiny. I went to check in the PC and I saw I got more than one shiny XD:

This time I got the medal and I am very happy, so I decided to share a small tip on how to speed up the chance to find one, hope this helps.

Pro tip: to get the last medal which is worth 100 points you must keep searching in the grass but because the process is long and tedious and may take time due to its dependance to luck, the only thing I feel to suggest to speed up the chance to find a shiny. To do so go into the tall grass, stand at the sides of the screen and hold down the directional arrow left or right depending on which side of the screen you are, and click "run" every time a Pokemon appears until the shiny one appears.
Here the image that shows better what I mean:

If you move in the grass Pokemons eventually appear but with this method you will focus the appearance only in that spot and you will notice how fast they appear. The shiny will appear first as regular Pokemon, but immediately after that a black square will surround the Pokemon and you will see the shiny variant. Throw your Pokeball and enjoy your 100 points medal.

The music is nice and gives a nice nostalgia vibe, but mechanics are a bit wonky when moving the character and I would have preferred a more varied Pokemon encounter along with some different environment but it was a nice test game nonetheless. I've also noticed that despite muting the music, it starts up again after soon, so the best way to mute it, is clicking on the speaker symbol on the tab.
It was nice testing my patience and finding the shiny, hence my 4.5 vote despite the flaws of something more similar to a test game than a full-fledged work.
