Thank you so so much for the feedback! I get that the upgrade system might feel a bit underwhelming, which is completely understandable and believe it or not, I am just as unsatisfied with it as you are! The only reason it's so plain and boring was due to lack of time, but if I'll find the time for it I'll be more than happy to expand it far beyond it's current horizon. And for the health bar? Welp, guess that's some more stuff to draw and I see how it's an eyestrain compared to the rest. But once more, real thanks for playing!
