okay so for your first game and also first game jam? its absolutely a great submission. although i would say you guys probably already learnt a lot throughout the process, from the players side there are a few issues to note. as stated by previous commentors, its kind of hard to see the platforms due to the color scheme. nothing was explained, so im still not sure what some of the side effects do, so a little work could have gone there. and some sfx and better music could have made it a better experience.
but damn for a first project this is absolutely insane. my first project was a terrible TERRIBLE flappy bird clone, and i couldnt even do that part right, seeing this feels like you have a great team going. keep participating and keep improving!
