Needs a lot of work I think. Some major issues here:
- Volume is extremely loud, and I used the ingame volume slider to lower the volume and still got my ears blasted out when I started the game
- Movement is janky and the camera flickers considerably as the character moves. Consider doing your camera movement in lateupdate or something to avoid the extreme character flicker
- Movement is slidey and doesn't match up with the animation
- Attack animations are only 1 frame and some aren't even animated. Needs a total rework
- Enemies don't really do anything.
This one is hard to criticise cause it's so unfinished. I think looking at how other platformers do basic things like movement and attacking to really solidify your fundamentals is the most important thing for you to grow as a creator. Take your time and maybe focus on really polishing basics to make sure you understand how to do them, even if it takes a long time at first you will get better and it will become easier.
Anyone can improve, and it's good that you managed to produce something for the jam, I hope you grow your skills and can make something much better next time.
