Hello, Thanks for the feedback, I'm glad you think it's nice and cute.
For the bug I had faced it and got the solution but didn't update it yet! (I didn't round the decimal and I think the long digits come from the Javascript common error when computing decimal numbers)
For the game engine I used GDevelop as it's great for developing a small game in a limited amount of time (This was a 3-day game jam submission)
For the tools I used Aseprite for pixel art and sprites some sound effects from the tool in game engine itself, and that's all about the tools the music and sounds I used are mentioned on the credit page at the main menu, It's free so I picked them.
Currently I have little time to update it cuz I'm making a new game.
The plan is to
-fix bugs
-update more hats
-fix sounds and BG music looping
-improve character movement as so many people mentioned it
-as you mentioned end game content I will try to update the leaderboard system but I'm a newbie at making game maybe it'll take time.
Thank you for the long reading.
