There are pits that players can't escape, and no way (aside from refreshing the tab) to reset.

The game froze every time I refreshed the page.

"Playable" in the sense that it has controls and a single beatable level.

This stands more as a proof of concept than an actual game. You have movement covered (and though some people are annoyed by Ctrl being a jump key, I don't find it awkward at all), and you have different mediums to travel through (yellow ladders, blue water, and red clinging walls). Where this game fails is in the design; so far, only Level 1 can be "completed", in the sense that you can grab the shiny object that signifies level completion, but it doesn't boot you back to the main menu once beaten. "Level 0" (the tutorial) has no ultimate objective, and Level 2 just goes on forever.

There's also a small sequence break in Level 1 where you can basically jump from the start of the game towards the door hiding the end-of-level macguffin. Simply get past the first projectile launchers, stand on that four-block-tall pillar, and then get a maximum height double-jump going left. You should cling to the bottom of the platform, and then can double-jump on top to get the key and collect the reward. I know you're SUPPOSED to go through the spiked wall-jump section, across the ladders, through the water and all the way around... but this unintended path skips about 90% of the level. Whoops.

So, uh. Presumably this is still a work in progress. But it really should be described as such if so.

Also, Ctrl is a terrible jump key. Please don't do that.

Other than that, honestly this has potential: the physics feel clean and fun, in a wacky sort of way. Once the bugs are all worked out it could be pretty solid with some more levels. (I assume level 0 is a tutorial, but level 2 doesn't end, and level 1 just kills whoever didn't reach the goal rather than actually ending. Getting hit by a cannonball causes the explosion effect to appear at your spawn point instead of where you actually die. Et cetera. All the obvious stuff.)

love your graphics but you can't jump over the water...
