A beautifully-crafted game! The quality of produced assets are incredibly high, especially for a three-day jam. The graphics are very well-polished--the monster design and animations in particular are amazing, and the visual effects successfully gave an 'unstable' feeling throughout the entire game. The sound design complements the visuals well and are nicely implemented--how you handled the sound of the approaching monsters and the transition from exploration to 'battle' comes in mind, for instance.
In terms of the gameplay itself, it was a bit confusing as to what I was supposed to do or where to go to since there are no indicators as to what goals I had to meet. I also found that sometimes the light bullets wouldn't launch properly if I clicked on the mouse too quickly in a consecutive manner...although I'm also terrible at aiming properly at the monsters. Additionally, the character's walking pace was a bit too slow for my liking--I was hoping that he could somehow run or execute a similar action like it.
As for the story, it's a wonderful take on the jam's theme! I liked the bits and pieces of the main character's memories scattered throughout the levels. Even without aiming to complete the game, I tried to explore all the areas so I can view all the memories. It would be nice (if you decide to do a post-jam, longer version) if you expanded the narrative more, as there aren't any concrete aims of the game in this version.
Final few comments on the audio: the exploration track doesn't loop well--whenever it loops back, you can hear a click. Also, it seems that the 'pick up memory' SFX is tied to the location of the memory picture instead of being a global sound? It was a bit jarring to hear it pan around when I move the character, although it ended up growing on me after a while.
