Impressive work! This would be super nice as a mobile game!

The tutorial levels are pretty clear, the design is good, the music sounds nice, and good sprite art! Definitely a nice job! :D

Great friggin work and congrats on your first public release =)
You did a really good job building up the mechanics, and provided some spots that were tough to master with the only one button. I also liked how it was all on one screen, with each level building off the previous. Was really cool to see the world build up from nothing, great implementation of the theme. I've got no issues to report, only praise for you fine sir!

Nice game with some tiny flaws though, I feel the one button mechanic fits the theme perfectly and this makes quite some potentiel for a mobile version as well, having the left and right borders of the screen kill you is a bit overkill i.m.o i'd say maybe either have them make you auto change direction, or appear on the other side ( like in mario 2 NES for example) this could add a bit to the mechanics, also having the jump on the button hold makes it a bit hard to chain jumps that are too close to eachother, i think this aspect could be improved by changes in the level design to better suit the mechanics.

Other than that i had a good time with your game, cheers and congrats :)

Nice game, I really like your approach to one-button theme, I use the same on a platform game too, check it out if you want. Congrats for your first solo development :D

Clever using of only one button ,cold be a cool mobile game .

Well done !

Nice game! The level design is great, and I like how you implemented the pretty popular "one button" theme. A nice-feeling game, I had fun playing it. Keep it up! :)

Great tutorial! It's a fun little game. :)

Great job! I loved the sound effects as well, and the mechanic and level design were fun. Thanks for a fun time!

Great work! Very fun game, very funny and satisfying SFX

nice entry! could also work very well on mobile ;)
