I like what you have so far, but it took me some time to get used to the longer jumps. At first, I missed them through the climb to the top of the first room and had to make my way back up a couple times. Maybe more speed would help, as others have mentioned. I then tried entering the door where you first start and collected a bunch of coins, but wasn't sure how to get the one's near the top...after poking around a little more I found the power-up. When I realized what it did, I went back to the highest coins and collected them. :)
Some of the jumps felt a little constricted with the tile right above your head. It wasn't too difficult to navigate them once I got the hang of jumping.
Also, I would like to see a little more color or a bit of change of scenery, background detail, etc. Lots of gray.
Nice work! Hope you keep it up!

Thanks for your feedback! I am definitely planning to change those things you mention, but ran out of time before the submission deadlline.
I'm kind of glad you had a "metroidvania" experience by accident due to the powerup and unreachable coins being in odd spots! I threw in the powerup right before I submitted the level since it was pretty much finished & it wouldn't even be close to a metroidvania without at least one powerup. There's also a couple impossible jumps in the starting room, but I didn't get around to putting coins or anything to make you want to go there. Plus one is covered by the heads-up display! Another thing I need to fix.
Some of those hard jumps might just need level design solutions instead of physics solutions. Some of those jumps were in there for me to test out how the movement felt. I don't think I would put in overly difficult jumps in the early game in a finished product. There should also be some more platforms so you don't have to start the whole room over when you miss a jump. I'll keep working on it, so I hope you don't mind checking on it again later!
