There is a problem with gameplay, you cant lose and nothing makes you go faster(you can add enemies or something under the player which can kill the player)
Character selection is surprised me, especially that each character has their own features. I think you should make some description of gameplay cause it is not immediately clear what to do. Well done!
Shooting mechanic is pretty good! It takes some time to learn how to use it properly but I like it :) Sometimes my character spawned inside obstacle but in general its a cool game( Especially Background). Well done !
Quite an interesting interpretation of the theme :) I like the idea that you can build your way to the next level by yourself, but maybe you should give player a bit more time. Well done, art are good too !
Nice work! I like this visual style :) I think you should use "Space" for jumping instead of "F"(Maybe I haven't read the instructions somewhere). And of course minimap is a smart decision :)
