honestly the most impressive part for me about this game is that (i think) it was created in Scratch! i've been an active user of it before and have been able to create short little platformers, though none that had scrolling or full-size bitmap sprites (i used this one technique where a color palette was iterated over and tiles were painted)... considering the engine limitations, i'd say the game is done well, despite its minor issues with collisions and such.
i haven't understood the point of the "throw out" mechanic, as it never seems to do anything for me. i've just been rolling a die, equipping it, and then walking up to an enemy and shooting. from the other comments, "throw out" seems to be the same as shooting, which seems pretty cumbersome compared to just pressing "X". that, and having to sort through a menu just to roll die also felt a bit tiring.
despite that, i do think that the game has its own charms, and it could even be improved further (still using Scratch or any other program) to become a neat little platformer!
