I liked the character design, but unfortunately the controls were pretty challenging. The character moved somewhat sporadically, and the arrow keys are on the same side as WASD on my keyboard, which made the key layout somewhat challenging.

I'm confused, did the other comments play the same game as I just did? :|
The character would zip across the screen, sometimes through walls but sometimes stop on invisible obstacles, seemingly independent of my inputs. 
With no jumping I would end up at the bottom of the level within seconds with no way of getting out? I could not tell if my gun damaged the big jar enemy down there and my bullets had such short range that I could not reach it unless I zipped back and forth across the room. I restarted twice because I couldn't tell if I was stuck or not and last time I randomly zipped into a room on the side where there were a few locations I could change the gun. With no limit on fire rate and enough range I could spam little red waves on the jar and suddenly it died? So I won?

I did quite like the rubber hose/cupheady sprites, and the level seemed pretty complex and interesting but with no real way of traversing it? I was very confused about the controls. :0

the character felt a little difficult to control for me. it would sometimes glitch-wallslide through walls / through the ground. i don't think i understood the gun upgrades, or what i was supposed to do. nice music (although a little intense, hah!) and visuals!
