Nice work, here are some suggestions
- Make a Game over screen, and alter the difficulty curve so that the only way to die isn't just sitting in one place and letting orders overflow you.
- Give your game the Overcooked treatment. Things like multiplayer, differing level layouts and mechanics, and possibly even some automation would go a long way to making the game feel more alive.
- Adjust the Movement, Seriously. The acceleration makes Santa feel like he's on ice, and it's not that easy.
- Controls: Why use the G and Space key as the actions?! IF you use WASD, try using K and L, which gives the keyboard a controller vibe and makes it so that there's less space to travel between inputs.
- The Music needs to loop. for me at least the song just stopped after one repetition. It would work fine if there was a timer for each level, but there isn't and it feel jarring otherwise.
- Art, Santa's Idle animation is almost identical in terms of speed and movement as to the Moving animation. If energetic animation is what your looking for, I say take a look at the Shantae games for Energetic animations.
