rube goldberg machine mentioned!!
This feels like something I could've played a bunch on coolmathgames, very fun and super impressive scope!
I think my biggest critique isn't even about the game- I think it would be nice if a more standard/readable font was used for important information on the game page.
About the game itself (I have a lot to say because it was very enjoyable and I hope you'll do more game stuff in the future!):
- Would be super beneficial to have a "clear all pieces in level" button
- Depth perception skill issue on my part, but having more visual aids in the tilemaps to distinguish the grid so I know what spots are lining up where I want them to easier would be helpful (e.g. if each diagonal row had slight variation from the next in a stripe-pattern, almost? so you could know "oh this is part of the slightly darker row, so it will line up with the slightly darker row over there")
- Not sure if it was intentional that pieces did not have to be part of the reaction to count towards the gold medal. I liked that it made it easy for me to get gold every time but felt like I was cheesing it (maybe I just lack integrity in games)
- The little bits of humour that allowed the dev's personality to shine through were a delight- I liked the 'lore' and the breakdancing dragoon a lot.
- When I got to the last level I got a little terrified at first glance of the 4million buttons but I think it was absolutely perfect as a final level- not so easy that it feels anticlimactic but not so difficult or frustrating that I didn't feel well rewarded for my time. In general for a first dev project it felt like your grasp on gameplay loop and how to reward the player was brilliant!
