Hey, that sounds really helpful and nice. There are two poeple working on music and sound now and a friend of me will build up the character now. But I am programming and not that talented in sprite work. But I think we need some more sprites for a cool game. The biggest missing part is a boss sprite. In my opinion a tree or something like this. The game is inspired by an old 90s game. You can take a look into my itch page there is a video of the inspiration game and also the current version of the game. The current character sprite is a placeholder. ;)
Currently I am building a upgrade system an more level. Which are with different targets as in the original game.
