Nice game! I love the design of the upgrade catalogue and the art style of the upgrade cards. The enemies as you go deeper were getting crazy which is awesome too! Using the harpoon is a double edged sword which is a great idea - on one hand you can use it as a long range weapon and on the other you can bring enemies closer to you. There are some note worthy bugs but with a little bit of polish I think this game would be even more fun to play - great job to everyone!
