Fun game!  The concept is superb, and the boss at the end was quite the formidable foe!  I appreciated the level design, and how there was flexibility in the number of coins needed to clear some levels, and how there were multiple ways to clear others.  That said, I did find aiming the cursor while platforming to be a fairly difficult task, but fortunately not too many levels required both to be done at the same time.  

I did encounter some bugs.  Running into a wall and jumping at the same time will cause the character's jump to be heavily nerfed, so it won't be able to jump onto whatever platform it was planning to, which is frustrating.  (Especially on that rising lava level!  I definitely missed having coyote time for that level, too, although that's a game design choice rather than a bug.)  But more curiously, I encountered a bug where I could generate infinite coins by shooting coins downward near the top corner of a room - the end result of which can be found in this screenshot:

Overall, you have an extremely polished game that is one of the few from this jam that is pretty much a finished product already.  It'd be amazing enough that you made this within three days for the jam, but I see you submitted with over a day left, so you really did this in just two days!  You should definitely be proud of what you made!

Bloody amazing! Nothing negative i can say about this game!

One bug i found was, on the very first level with lava, when i would go down (to the lower platforms) and shoot my coins directly down in the ground, they would actually destroy themselves with the lava particles so there are some buggy collisions there.

Great work!

Hello, I love the game. It's fun but not only that, it's thought provoking. I appreciate how the game teaches you the basic mechanics and then tests you. I noticed that once under a platform, the game stops you form picking up any amount of coin that would get you stuck, I'm quite interested in how you pulled it off, I have a theory but I'd appreciate you sharing that information. Anyway, like I was saying, this is one of those games I wouldn't mind playing in my free time, so well done, I don't have any complaints, it's a full-fledged puzzle platformer. Kudos.

That's definitely one of the best games of this jam! I love the polish of the game, nice controls, level design, cute graphic, it's all so good!

Its too good

Beautiful Game very polish, cute graphic and great game design.

It would be nice if you could make platforms with spitted coins or when you spit coins  would give the player some kind of air boost. 

Damn! Nice game! This is a great concept for a full-length game.  Good work

Fun little concept! I feel like the jumping feels a bit "heavy" at times and i'm not sure if this is what you were going for, but interesting mechanic and cool gameplay :)

Please - make it full release. Your game is one of those rare gamejam productions which present quality of best indie games available at all biggest game stores on consoles and pc. The depth hidden in multiple mechanics connected with coins, tricky level design, pleasant graphics, music matching to mood and artstyle. I'm amazed. Great work. Love it. Worth more than one coin :)
