Very fun, the controls respond well, the universe you created is interesting and encourages exploration. I really liked the tracks, very comfortable to listen to in loop, it would only be better if there was some sidechain/volume fade between the gameplay track and the theme that plays when it switches to "meg mode", so as not to get a dry cut between the tracks.
I also found some NPCs near action locations a little annoying (for example, the npc who keeps asking to use the hammer on the broken wall). When I use the hammer, it ends up activating the conversation with the NPC at the same time and I need to read the entire conversation again to be able to play again. And some NPC's don't give new information or talk about their world, they just repeat what others have already said.
The SFX are cohesive but could be more alive, brighter, with more layers. They would make this universe more palpable that way.
Anyway, an excellent game! I gave the maximum score to everything because I believe that the negative points do not significantly interfere with the good result you managed to deliver in the short time you had to develop!
