I liked it! Art was good, audio caught me off-guard a couple times in the best of ways :)) The caveman model was really funny too.
The t-rex is difficult to avoid, I ended up just going for the mushroom guys furthest away and bolting as soon as the roar happened- are there other ways to play around it than just running away until it goes elsewhere?
I liked the easy mode inclusion, came in handy after beating the first level a couple times and wanting to rush to the second. Having two separate gamemodes is often pretty ambitious for a jam like this, but you definitely did a good job at fitting it all in.
I encountered a substantial bug, where taking one of the crystals in the second level prevented me from moving at all afterwards. It seemed to happen after picking up the colour building crystal or the fire hydrant crystal- unsure about the others. I also couldn't hit the fire hydrant after picking up the tree branch- I'm not 100% sure if that locks me out of completing the game as I shortly afterwards got frozen after picking up a crystal 😅
Overall cool! I liked playing this one and the caveman will be burnt into my brain for a long time :)))
