Hi, thanks for playing the game, we hope you had fun 😊 Cheers for the feedback, it is appreciated!
To address the glitches, we watched the video and it seems the collision is working as intended, to drop through thin platforms you only need to tap Down, if you press it longer you'll drop through more (this can come in handy for the first end of World boss), it takes a little bit of practice to get used to.
As for the high score issue, it occurred if player 2 was the only player to place on the high score table, however thankfully that bug was fixed in V1.2 🙂
And to answer a question you asked on the video, the letters at the top spell "AMPED". If you collect all the letters on a World the following happens:
1. Enemies which are KO'd in a chain drop large scoring items until the end of the current World.
2. The end of World boss is harder, but also drops a high scoring bonus item when KO'd. You need four of these items to reach the final World (World 5).
We enjoyed watching your video! If you have any further questions we'd be happy to answer them 😀
