Thanks! I loved the video - it's really well made :)
If you're interested, I've written a bit about the game's design process, and a bit about some of the difficulties I've had coming up with ideas to expand the game.
After going through the blue gate and activating the checkpoint to replenish your resources, you can send a skeleton to the left to hold down the pink button in the water. Make sure the skeleton has a long enough run up so it can fall into the water.
That's a good idea - I've created a BBS page for the game now: https://lexaloffle.com/bbs/?tid=33693
I've also added the link to the game's description.
You'll be able to download the game as a cartridge from there. Alternatively, you should now be able to find it in Splore under Jam games now.
