I'm really glad to see that you like it!!
You're a definitely right, the thing that I wanted to polish the most is the player controls. They're a little unresponsive, Sorry about that.
The bugs I made this way on porpuse, to actually feel like Bug and not Just Power ups (the reason for the quantity as well)
And for the art I wish I totally knew what I was doing, but I actually recent had a huge inprovement in the past months, but for instance, I didn't know How to make the boss, so I Just followed my heart :D
Thanks for playing and for the feedback!
