My main issue with the game is how slow it is in general. Not only does the character move quite slowly, but the cutscenes and text boxes are also very slow. The character also really loves to clip out of bounds, especially near corners, and the game has a huge lag spike when the music loops. This is probably because this game uses a very old engine from 1998.
Aside from all that, the story concept, and how it is supposed to be an alternate story from Yoshi's Island, is quite clever, and I'd really love to see more of Wick if the engine can be updated to a newer, different one. The idea of burst flight by holding down to build up power, and using that power to fly while in mid-air is quite fun to control, even if the controls can be very complicated during the first few minutes.
Overall, the gameplay is very slow, and boring to have some fun with, but the idea is quite great, and could be executed quite well in a potential sequel!
