First, thank you for your opinion. You saying the game was fun is a great thing to hear, as this is my first game jam
For the controls, as I play-tested the game, I got used to them, so that was my mistake of not having other people play-test the game more (my friend also got used to it). I would keep that in mind for my next game
Most of the art was added in the last 2 days, and I needed to redesign all the levels and fix a lot of bugs, so I just added it and hoped it would look great, since most of the world was a last-day feature. I wished I had used some outlines for the characters and the world in general.
The attacking was taped together as I coded the player movement a few days before the game jam. The attack was much harder, and I had to redo it multiple times, and it still has bugs, like you should be able to hit multiple enemies and give them knockback
In the last few days, I was overburnt due to having final exams in the first 4 days of the jam, so I couldn't add a lot (more enemies and bosses, more animations, more levels ...), and jucing up the game with sounds and particles was one of the things I had to sacrifice
In the end, I would like to thank you and every other guy who rated my game
The game turned out to be good, but not as good as I wanted, but good enough for my first jam
Thanks
