Hey, thanks for the feedback! A couple things about what you said, though: You can also use Ctrl and Shift for shooting, the mouse isn't the only way to do so. (It says so in the description on the game's page as well) Additionally, I was trying to make all of the blind jumps less blind by having trees on the platforms that you can see from the top down. Everywhere where you had to jump, you should've been able to see a tree lurking up from a lower platform. I know of an issue though where at one point, you have to jump onto a platform with enemies on it that you can't see, so you can take damage that way which, I agree, isn't very nice.
Also, I really would like to expand this game with more abilities and stuff like that, so thanks for giving me the motivation to do so! <3
