The game is very pretty and it's impressive all you did in one week :D this could very well be a demo for a full game !
One of my complaints would be the level design ? I didn't know you could interact with NPCs so it was just very big sections of walking for me :/ some of the tutorial was a little confusing too (I kept trying to water the dead(?) flowers) and I wasn't able to use the flashlight in any fight, it didn't seem to do anything. The current level design gives it those dreamy vibes but I kind of walked past it since I felt I was meant to keep going forward until the next boss u_u. The combat was alright, like a first person bullet hell type of game. It felt a little too easy (which is better than too hard anyways) except the onion who was the tankiest enemy ever and made me question if I was playing the game right >:'(
It's still really impressive and has a lot of potential though ! You created a really interesting world with very few hints of the lore (maybe the NPCs had more lore) and it got me invested to what was happening in your universe. Great game, I'm sure a full-length version would do well !
