Awesome, thanks a lot! I enjoyed watching the video. I liked how open minded you were about the games and that you gave them all your best.
I'm impressed how well you solved the puzzles in my game. It can't have been easy doing it while streaming and after already having played games for nearly three hours!
In the video you asked about which engine I used. As you speculated, it's my own little engine that has slowly taken shape over the years I've been doing game jams. It's quite limited in many ways but it works well for me since I know it so well by now. And I guess in a way the limitations help me with not scoping the games too big. Here's a screenshot of how this game looks in my editor.
Take care and thank you so much for the coverage on your stream :)
