This was good! The presentation was well done and I thought the soundtrack was especially good and accompanied the visuals very well.
The light mechanics were clever and created some interesting puzzles. I would've personally favored some more complex puzzles over the timing based platforming challenges. I do think the game could have done a better job introducing some of the mechanics as it took me a bit to figure out what was going on at times. Some better visualizations and some very simple introductory puzzles could help with this. Also, maybe highlight elements that changed for a brief moment when they're revealed?
The story was a little predictable (although I can't really blame you for the content warning at the start). Despite that I felt like the dialogue worked well for me, especially the relationship between Bell and her Sister was well executed. Even though I knew where it was going I enjoyed discovering how it would get there.
All in all a great game! I'm interested in seeing how it develops further.
Thank you! Yeah the light mechanics were a bit tricky to make puzzles for. On top of that, since the cutscenes took so long to make, I didn't have much time to make puzzles, so I ended up opting to have more simple timing stuff. I definitely would've loved to make some more complex puzzles for the game, just didn't have enough time.
The introductory puzzles are a tricky thing because I really wanted to try and communicate the main mechanics without actually telling you anything. I think that some of that worked, but I get that some of it didn't. I'll think carefully on how I want to change that for the future. Also, I like the suggestion of highlighting stuff when it changes - that could definitely aid in the puzzle-solving process.
I'm glad you liked the story! I totally get that it's a bit predictable - I realized pretty early on that I'd have to have a content warning, and that would end up spoiling the game pretty bad, but I don't think there was any way around that unfortunately.
Anyway, thank you so much for the detailed feedback! I'm glad you're looking forward to future developments - I'm planning on this eventually becoming my first Steam release, but it'll probably be a while before that happens. Feedback like this is invaluable toward getting the game ready for that, so I really appreciate it. :)
