First of all, good job creating this game! I quite liked the Efteling theme.
I have a few improvement points:
Combat: During the 1st half of the game (gem search) and when I encountered the mushroom enemies for the first time. It was definitely a bit sudden. An onboarding/tutorial for the combat would be highly appreciated, as it is only briefly explained with a left click at the start of the game. I do think the combat window pops up very fast and makes me feel like im on borrowed time, which personally I do not like. I think it also takes away from the explorating/finding gem experience, when I am looking for gems I don't expect a fast-paced combat system. I think it would also be a pleasant change to give a bit of leeway to the player when tracing the shape, as the trace had to be quite precise.
Map: The map layout wasnt necessarily bad, as I managed to find all the gems in a pretty short time. I wouldnt mind a bit more incentive to play though! A bit more of that efteling vibe : )
Boss Level: This level needs a few more iterations. I don't like the amount of text I'm being shown when I fight the boss. I want to play a game, not read.
The camera is a bit scuffed. Especially when it zooms to the boss (which is a good idea) but afterwards it zooms back to 1st person view and I loose complete sense of what I needed to do. Where is her attack going to land? Which track do I go on? Am I going to die? What do I do? (edited)
The teleporting of the boss also seems very random? It's pretty difficult to charge up the bar. Its gets pretty frustrating, and once i've charged up the bar I realise that the attack barely did any damage! I have to once again try my best to track the boss with random teleport pattern.
The dodging doesnt seem very alligned with the gameplay, and I can't tell when I should use it. Consider maybe changing the dodge to a more 'dodge as long as you hold in the button' kinda thing. A small tutorial for the dodge during the boss fight would've been nice.
Honestly I didn't feel like the dodge or switching tracks did anything. There was no feedback if I had actually succesfully defended myself or not. I did not manage to finish the game due to the boss.
These are mainly improvement points, but I think the rest of the game is pretty decent. Especially looking at the size of the team! The voice acting was pretty funny.
