Very nice game! It looks great and it's fun to get the upgrades so you can explore further areas :). Probably my only complaint is the controls - the jump feels a bit weird how you dash forward when moving horizontaly and can't move much in the air. It's especially strange when trying to jump over a wall or when on "stairs". Oh, and I also tried to jump near the spaceship so many times and it opens the menu, haha :D. I like the lights and the death effect :). Well done game!!
