I liked the style in which the game is made and the way the character moves his little legs when moving.
I only got to the shell level, I couldn't jump onto the platform there (possibly because of the sword upgrade)
Thats true, If that was on one of the first levels then i think i know why, I think i accidentally started players oput with 10 points and they were able to buy the upgrade, but now in my update you can not buy that upgrade until the end of that level. You can try again with the update or if you dont want to download it you can go into the files and delete user and it will restart you.
