I kinda wish the scale gun was introduced earlier, since it could have been used for some really interesting puzzles. Though I get that this was probably cut short due to time.
Yeah... we needed 2 more hours to get some more levels in. The ray gun was incredibly buggy for most of development, so we couldn't focus on the levels for until the last 24 hours.
Can definitely relate to that. I spent most of the jam worried I wouldn't even have levels by the end of it. Two thirds of the levels in my game were made in the last 12 hours.
