Thank you so much for your words. I knew most people wouldn't prefer the music because it's a little bit uncommon. But I kept it anyway for maybe those few people who would enjoy it as myself ^^ Just because it clicked for me with the character design and aesthetics. You made me immensely happy with your comment ^^
The fact that you love NieR makes so much sense! It is something that crossed my mind and some ideas I wanted to steal from it, like to add some more gameplay sections, when you go to the rocket for example to turn into a different game .^^ NieR is on top of my wishlist for a long time, because I played only for an hour or something because my pc could barely handle it. Thank you for reminding me again that I need to play and finish this game, I totally will.
As for the game.. sadly it's no where near a complete experience, what you say about progression is absolutely right, there must be a sense of progression. As also content and variation! Points of interest, collectables, more enemies and more gameplay interactions with the player and the world. Sadly it took me so much time to polish and find the right mood for the game, that I was almost out of time and I added everything at the last few days. I believe the game could be developed a lot further into a pretty good experience. I was burned out from the last push and didn't continue working on it yet, but a comment like yours totally makes me think of continuing it ^^
Take care!
