Thanks for giving it another try , now that the jam is over and so too the holidays I can get back to working on finishing this project, thanks for the valuable feedback I started implementing changes today, and i must say that I am really pleased with all the feed back I got and ways to improve, I have already removed the need to collect gems as the main focus, I gave the player a shuriken that does 1 damage and is unlimited and the kunai that uses the gems and does 4 damage and also increased the health on the enemies I have also added random drops to the enemies as the currency to buy power ups , to give players a reason to kill enemies. thanks for your suggestions, I have not updated the game on the game page yet but I will at the end of January, when I update the UI , menu ,boss battles and make a trailer, Hope you give it another go when I am finished !
