I have to say I love the goose's animated sprite, and the cherry blossom was a very nice touch that was added, and when they switch to snow during wintertime, it is amazing! Switching seasons was a fantastic gameplay mechanic, and I loved the scenery and the animation that you created! Certain platforms only working in certain seasons is genius and fits with the shifting realities theme! I like all the different platforming mechanics in the game! A few notes I have are that the music doesn't loop (it gets very repetitive quickly) and when I die, it restarts the scene. Maybe a checkpoint? Would've loved to see music change during seasons and sound effects. Also, I can get infinite coins because the coins respawn again (and coins don't do anything; I suppose maybe add a feature where you can use the coins to buy something, perhaps). Also, in the death scene, I suggest adding a death sprite animation. Another thing I wanted to mention is perhaps improving the camera by making it fixed in some areas because it's too zoomed in, and platformers usually have areas where they show you the entire scene for easier player navigation. The area with the 4 snowmen was challenging, and I gave up on that area, although I wish I had continued beyond that. Perhaps add a checkpoint there? A very important suggestion too is perhaps adding like "/5 crystals" collected so players know which level or how far they are in the game for more motivation. It's an awesome game and has amazing potential! I loved it a lot, and I know I was critical of it, but that doesn't mean it wasn't a great game, and you should be proud of it! Splendid work!
