I enjoy the concept a lot; the idea of playing through a game and stacking weapons is pretty fun. Though the game could have been polished a little more and some things thought out better. Balance is an issue, some weapons are will either wreck shit or help in no way shape or form. Some combos work pretty well and some don't which is good and bad I guess. Jetpack early on is probably one of the worst combos you can get, I managed to snag it about 2 levels in and backshot too. With the Thwomp like things swinging above my head and walking poison spitting guys below, hopping up every time I fire is really dangerous. Though coupled with something with gravity or aimed down, then yes Jetpack is OP as you say. Any laser pretty much wins the game, I got this early on in my second game along side poison spitter and I became almost indestructible aside from some failed jumps into spikes. The control feels a little too light if that makes sense. Jumps for some reason aren't as tight as I'm used to and making precise leaps through poison and metal thwompy things is really difficult. Maybe that's just me. I understand that you wanted to make a game packed full of chaos on the screen, but I can recommend that screen shake is toned down slightly. It became really difficult to see anything with so much shaking, I couldn't really see the final boss clearly even though I had it pinned into the wall with the laser. Overall; I really enjoyed the concept and if it was expanded on a little more with a few tweaks here and there, perhaps extending the amount of levels a bit more, I would enjoy the game much more.
