Congratulations on the game! There is clearly a lot that you have put in to this and it shows! If I could give any feedback, the sprites appear to blur quite a lot on loading the game, which typically will happen in editors if the settings are not correctly set up (for example, unity uses a filter method that will usually blur pixel art!) I also noticed that scrolling the mouse wheel zooms the background in and out, but bugs like this are expected when you only have a short timeframe to work with! I also think you would benefit from looking into tiled-view when making your tile maps in your sprite software, as you can see the edges of the tile sprites in the cave, and tiled mode would allow you to draw a continuous pattern that will blend in seamlessly. I was impressed with the game and though that the use of a 3-second rewind timer was really cool! Keep up the great work and I hope you had fun developing this game :) If you get a moment, please take a look at my submission and let me know of any feedback or criticisms you have! I would really appreciate the opportunity to get the point of view of another developer in this Jam :)
