Neat little game you all made for the jam. Well done!
The game looks and feels pretty good, except for how the crystals work... There's just so little feedback on how each one works and little consistency on their timing. It would have been nice to have a mouse click or other input be used to activate the crystals instead of a timing, allowing players to have more control over their movement. Not to mention that the green crystal is easy to break a level with since it appears to break level collision. I got stuck inside the level the first time I used it lol. It would also be nice to have a UI counter for how many crystals you have. Dialogue was a little long and confusing just because of the two speakers. Having a single speaker or the speech bubble move with each speaker might make that more clear though.
I offer so many areas of improvement only because I REALLY like what you have done here. This is a cool take on a platformer and with some polish, you could be on to something. The game handled well outside of the crystals, the presentation was clean, and the design foundation is solid. I don't ever want to pressure a dev to continue working on a jam game post jam (jam games are great learning tools), but this is a really cool loop and I'd love to see what else you can do with it. Super cool game, y'all. Keep up the good work!
