Thanks for your feedback ! I must admit I forgot to erase the connection when your mouse is over the battery due to how clunky the coding is... and I also agree with you on the 2nd boss being too easy, I was afraid of making anything difficult, and I really wanted everyone to be able to play the whole game. I'm working on an update to rebalance evrything and fix all of the bugs (like the weird screen flickering when you shoot). When it's released you can check it out for increased difficulty !
Cool, I will look forward to it! I should have mentioned, it took me several tries and a bit of luck to defeat the second boss with my self-imposed restrictions. I actually really like how the game's base difficulty is very accessible, but there are opportunities to add extra challenge (like using fewer modules) if you want to.
