A fun experience. I liked having the 3 mini games to try out, and loved the detail of the hand on the joystick moving!
I think it was a clever use of dev time to re-use your upgrade system in multiple games. Music and SFX were fitting. Great use of the theme.
Jumpy Bee: My least favourite of the 3. I was functional, but for me the values for the gravity and jump/flap force need a bit of tweaking.
Space Survivor: I enjoyed this one, and liked the upgrade system, but felt that the coin drops were a bit infrequent. Which meant multiple rounds in a row without being able to afford to buy new upgrades.
Gold Digger: My top game of the 3! Really liked this one, but i found quite a few occasions where the blocks with Red & Yellow gems didn't drop anything when destroyed, which was slightly frustrating when I'd chosen to target those blocks expecting a good reward. As with Space Survivor, the drop rate of gems is a little slow to start with, meaning that you can have runs where you don't quite have enough cash to buy upgrades. I think in these types of games you should give the player some low hanging fruit to get of the mark quickly, and hook them into the game loop.
Overall great job!
