Hello! I had fun playing it, but I do not know where to go after the first boss because I cannot see a door or a hole to go through or anything of the sort :( If you could help with that I'd really appreciate it, I would love to finish it!

Still, I really liked that boss (actually died to it a couple times!). My favourite part of the level was that part where there was a difficult jump to make and if you don't make it the path underneath is blocked by a crate, because it forces you to use your gun and thus learn that you can destroy them that way. It was a very nice execution of a classic game developer trick >:)
