Hey, I really liked this game! It was short but sweet. Your teacher must be amazing haha. The voice lines were great, and the gameplay was actually pretty fun.
I really liked the dual purpose mechanic of the club throwing. Using it to kill enemies but then also using it to interact with the level is really clever design. I think an improvement to it could be that you can also debug with it, so everything is done with the club.
I liked the old school feel of the game, and the visuals were pretty coherent. I also loved the crunch machine at the end.
The mech part was a bit weird to me because it didn't really have a big challenge to it yet I still kept taking damage. I think what you could've done there is just make the enemies appear from the front or something to make it more skill based and to stop the player from taking random damage. Still though, it's really impressive that you managed to get basically an entirely different game into the main game, and it worked well as a refreshing variation.
Overall, really well done!
