Good lord this has a lot of puzzles for a jam game, you guys are insane.
This is a very creative & well made brain tickler (Thank you SO much for the quality of life stuff like the hotkeys & speed up button), honestly I think my main concern is you've done too much with the amount of items and objects, rather than relying on puzzles that focus on a couple of key objects.
That's not to say this is an issue, I think the mechanics of the boomerang have been well explored & the puzzles effectively test my brain, I just think the amount of different mechanics overwhelmed my brain a little bit by level 20, so I might need to come back at a future date when I'm not already bogged down by the fact I'm trawling through jam games already lol
With some light polish on the visuals and music, I could see this being a full release.
