Thank you so much! Those are very kind words and I appreciate them!!
Yea, I totally get that. A hint system of some sort would definitely be welcome. If I'm going to further develop it I will look into adding it for sure.
I'm actually not entire sure where the size is coming from. This definitely isn't my first rodeo by far, so I'm pretty good at efficient code/architectural structure and I'm definitely not hardcoding 20 scenes. My best guess is because I just loaded in all of the asset packs I'm using or thought about using into Unity, that it's just compiling *all* of those assets into the final build. I'd have to do some testing to confirm that, but you know how game jams are with time... I figured my time would be better spent improving the game than optimizing the file structure behind it ;).
Also agree on the camera controls. Ideally I think I'd want to have the mouse play a much more vital role, so you don't have to rely purely on the keyboard for the controls. And maybe even look into more of a free mode of such. I felt like I couldn't really change it too much without going too far away from the theme, but in a future update I might be a bit more loose on that. And this was also another case of time constraints, where I didn't want to spend hours with the control scheme instead of spending that time developing levels and content.
Thanks again for all your insightful feedback!
