Indeed, I had to download the .exe AND .pck as a windows user -- I just skimmed over the instructions the first time like a goon. :)
The music choice is pretty good. I was absorbed into the game from the title screen music, but on start, the level music was even more engaging. I also appreciate that you put in a sound effect cues for jumping and death.
My little buddy controls pretty well. My only problem seems to be how he slides a bit when he lands, making the single-block jumps rather tricky. This might be common in platformers though? I recall Mario being similar. No traction in that plumber's shoes I guess.
His idle animation is cute. His square head and stem body allow him to sometimes "perch" on the edge of a block instead of falling to his death, which I really appreciate. Overall it's a fun little game, and I find myself having to exercise patience and timing to progress.
And then I got the golden block!!!!!!!!!! :D Yay!!! It took some doin' but damn I did it. You're right that I was proud at the end of the level -- but rather than being proud of myself, I'm proud of YOU. Thank you for sharing your game with us!
