It was ok
The collection was ok, but I found that some of the controls were a bit iffy and there were a few glitches.
1. On the swimming one, the player would phase through the wall before actually hitting it.
2. On DK, the jumping animation would play as long as the space bar was held down, but DK would go back to walking if you let go, even if still in mid-jump.
3. You actually have to WALK on moving platforms? That's not right.
4. The tennis ball kept getting stuck at the beginning of level 1 every time you respawned back at the start.
The controls on the racing game were particularly bad, and the hammer game was just boring.
5/10 because it was fun for a bit but needs some refinement.
