Very fun game! They player controls are perfect and time to take back the harpoon makes the challenging (which is good, in my opinion) Now, the game needs a lot more details to make it enjoyable (very small things that together make it more fun), for example: particles (walking, throwing, etc.), environmental (textures, bugs moving around, etc.), sounds (music, etc.). With these the game would be really fun! Great job with this game!
Would love if you could check mine out too! Or not, no pressure ;)
