Thank you so so much for taking the time to review our little game as extensively as you did! It's very much appreciated by the both of us :D
We are both really glad to see you like our game, and the graphics especially! The snow is made of actual particles and the snowy mountain is a tiled texture that is very simply made by drawing a (dithered) gradient in Aseprite and (ab)using the Jumble tool to make it all swirly, and chipping away some pixels at the surface for the bumpy look.
I do agree that the audio is better off when it's not panned so harshly, and it was actually an accident! We used AudioStreamPlayer2D (in Godot) instead of a regular AudioStreamPlayer, because my eyes skipped over the existence of the AudioSteamPlayer node and somehow thought AudioStreamPlayer2D was the usual choice for 2D games. Glad you pointed it out though, so now know the difference between the two!
The idea of adding the ability to skip the tutorial, and idea to structure the tutorial in such a way that the player cannot pass the tutorial without switching colors, are both really good suggestions! And so is having the game reward the player based on the difficulty that the RNG presents, though I'm not sure if we would want to keep the random aspect of it at all, or just have a couple of pre-designed sequences of obstacles (that might be in a random sequence themselves) and rely on speeding up the game and introducing different (more difficult) obstacle sequences for increasing difficulty - if we ever are to continue working on this game, that is! The adaptive audio suggestion would be a really nice addition and very fitting for when the whole game speeds up.
Allowing different input schemes is definitely a good point - just makes it playable for a wider audience and that's always good. I never knew there were so many input schemes to keep in mind, and it never crossed my mind that people on a Dvorak keyboard would use different keys to play games, while it makes so much sense! (I also just found out you can edit input maps in Godot. Looks super handy!)
I probably skipped over some of your points (cause there's so many!!), but I definitely learned a lot from your review, both about game design choices as well as some Godot features by giving me the drive to actually look them up.
I can't speak for Romano cause he is currently in a very busy period of his life, but I will definitely keep making games (recently started on a bigger, more long-term project!) and participating in game jams!
We're not sure if we will continue working on this game, but if we do, this itch.io page will most definitely get a makeover. If not, I'll be sure to keep it in mind for any future games!
Thank you! :D
