all i gotta say is wow. Wooooow. Legit, i can see this becoming a mobile game for profit. It gives me a lot of merge dragon vibes. I love the art and how addicting it is. I wouldn't call it simple... considering how complex the upgrade system is... but i will say its very assessable, easy to understand and pick up and play. As of my spending a hour on this, here is the progress i managed to screenshot


i swear i got all 3 milestones for the first 2 worlds, 2 for the third world and 1 for the forth world. I would keep playing but my tab accidentally got reset. With all my progress.
As for critiques, the worlds are not all that uniqe to each other. Im not expecting much. But anything other then the same grassy land would be nice. I would also like a reward for getting all 3 milestones in each world. Like maybe a huge dragon or something. And i guess if you want to go the extra mile, each world could have a gimmick to have them each stand out other then just having higher coin requirements. Man... i wonder if something cool happens if i got all 12 milestones. I was so close to finishing! And my hand hurts... worth it. Also uh... a in game tutotial on what grass hoards, caretakers, mages, ect do would be grear.
A general tip i give everyone is to use the rating period to finish anything left on the cutting room floor and post it in a mid rating period patch or post jam patch. But... i have a feeling your pretty satified with this.
So... i got a offer. If you guys want, im willing to collab with your team for the next mini jam if you want. Dragon fans unite! And all that. If you want to try anything on rpgmaker, i can help.
