I had a lot of fun with this one! Good controls, good progression of upgrades. I love the hidden places that you put in to get the extra gems and try to get all 50! I will probably play again after I play all submissions to try to get all 50 of them. And thank you so much for making gamepad controls, and also making it where you can use the left stick instead of just the dpad to move! This is the first submission I have played where I could do that!
Feedback: Jump and dash especially feels a little robotic. Are you supposed to be able to dash in the air multiple times without touching the ground again? The only real bug I found is that sometimes I would land on a spike and not get damaged. If you really need me to I can try to do it again or find where I did it at. Otherwise, everything seemed to work just as designed!
