Thanks for the great feedback !
Art is not something I'm really skilled at, so I'm happy that the quick drawings I made in gimp were not too bad... I always try to animate the UI as much as I can, I think it's an easy way to give more life and personnality to a game. As for the planets stacking, I was like "I want the character to hold multiple planets at a time but he also needs to hold the rocket at the same time.. let's just make him stack the planets", I really wanted to make more planets so that the effect would be funnier but I didn't have time in the end...
As I said I really wanted to make more planets and I even designed 2 more, but I didn't find an interesting enough way to play with the color matching mechanic beside "mash C to get the right planet at the right moment", so it felt like a cheap way to add difficulty... that's why I ultimately stayed with 2 planets only. For the forgiving accuracy, I figured that it wouldn't be much fun to fail a level right at the end because you didn't aim well, but I still wanted it to be a sort of final mini challenge at the end of each level, that's why the goals are moving so fast in the last levels. I think short levels were the best choice because it allowed me to design levels pretty quickly and to add enough new ideas without making the game too long, especially since I didn't add a save feature or a level select screen (which I wanted to do but didn't have enough time to)
Displaying the controls on the title screen are a nice and easy way to tell everything without losing too much time doing a tutorial for example. And yeah, since switching planets is only introduced halfway through the game, I figured it was necessary to remind about it when it finally appeared x) For the rocket, now that I've replayed the game with a fresh new look, I think I should have made it a bit more responsive, because some obstacles near the end of the game seem almost unavoidable if you don't know about them in advance, so I am a bit disappointed that I couldn't realize it before the deadline. Oh well, it's a traditionnal game jam error !
Music and sound effects... I spent way less time working on them than I usually do, so I didn't have the time to tweak the sound effects like I wanted to. In the end, I think it could have been worse, but I'm not satisfied with some of them yet (the victory sound for example is a bit underwhelming I think, it just sounds like a coin from a Mario game). As for the music, it's always my biggest enemy in a jam. I have absolutely zero musical skill, so in the end, I just do like I always do, which is taking the percussions in boscas ceoil and making a rythm which gradually speeds up. But this time I decided to make it speed up between levels instead of during each level, which ended up way better than I expected x)
I switched over from Unity to Godot because I felt Unity was becoming a bit too complicated to me... and most notably because I like Godot's interface and the fact that it's really light and open source. It's actually only my second game made with this engine, and the first one was a FPS that I made during another game jam... while learning the engine at the same time ! It's definitely something I would recommand anyone not to do, because for me at least, it was pretty visible in the game x)
Well thanks a lot again for your really detailed feedback, it always feels super nice to receive ! I ended up answering like you did in the comment I left on your game, because reading it was really fun and put a smile on my face ! Aren't game jams wonderful ? :D
