I just finished playing the game,and I loved it!
Got stuck for about 20 minutes on the part where you need to touch the radio and 20 minutes for the code,but the rest of the game went smoothly.
The game itself it's pretty short and there's not a lot of actual gameplay,maybe adding more interactions with objects that unlock other memories that might bring you to an alternate ending or something like that,I found the story really interesting and original and I loved the underatle easteregg too! XD
Even if it's your first game is really well made.
