Actually i agree with you. I think i should remove the disappear time of coins/healths. And also you can avoid the laser beam. As i mentioned on mini tutorial screen(yes i know its worst of its kind) you can dash with right mouse button to avoid lasers, or dodge bullets and slimes.
I think "if you death you lose your weapon" is main piece of game. But i can make more powerful start weapon and maybe increase the gold drop rate.
And i want to add something, your feedback is really good for me! Thanks for your time, have a good day!
