this is a really good game! one thing to consider is making it more clear if there is an end boss or something- i wasn't sure if i should continue playing or not after reaching level 5 or so. that being said, great game 5/5!
Thanks for the feedback, happy you like it! That's actually a great idea, maybe I could add a short cutscene, in the beginning, to introduce the boss to the player and make clear that thas what the player is working towards.
