This is quite an awesome interesting game, the switching mechanics concept is nicely integrated here in this game. However, I find it really difficult to pass the level as the level design is not up to the mark and this is the main point you have to figure out to make this game enjoyable. Next, the movement mechanics needs to be polished more along with the controls and animation of the player. Integration of sound and such key elements are missing in this game which could have possibly played a key role in making this game feel good.
Looking forward to your upcoming projects ahead of time. All the best for your future projects.
