I loved pokemon ranger as a kid, so this is a really nice hommage. Sadly I could only experience it on a trackpad, which makes this way harder than you intended. But I did get actually angry that my cheese was being stolen, so your game did what it was supposed to do!
Edit: saw there was an upgrade station, tried to go back and lock in, but trackpad too hard man. I'll try again later with a mouse :p (you need a mouse to catch a mouse)
