I'm on Android 11, game version 29005750 from F-Droid. There are a number of technical issues I've encountered thus far:
- The app is very prone to not just lagging, but cases where some blocks visibly drop 0 coins when broken, seemingly because some entity limit has already been reached. I would suggest allowing broken blocks to spawn 10-value coins or even 100-value coins once the multiplier is big enough.
- Trying to start a new game via button literally never works. Usually it leads to a black screen for me, only once was the screen white. Regardless, I always need to restart the app to begin a new game.
- At high enough speeds, coins are sometimes capable of clipping through the puck, forcing score/multiplier pentalties (if using Compound Interest) despite not truly missing the coins with the puck. This is most noticeable with max Coin Magnet and little to no Viscosity in the later levels, as big clumps of coins will fly directly into the Puck, but then as it eats them, it just farts out a few of the coins into the pit for no reason.
- Sapper and Kaboom also make coins capable of clipping past the bottom edge of the screen itself, with strong enough explosions. This results in the level becoming unbeatable, as such coins never despawn. If this happens, the level inevitably becomes nothing more than a ball juggling simulator on an empty black screen, until the player accepts a loss or restarts the app.
- I think some of the combo-related upgrades should be described better. Shoot Straight and Sky Limit both say they offer more coins, but Hit Streak and Picky Eater just sound like they make you do whatever's described. Hot Start and Compound Interest do the same, but those two at least have the advantage of having names that help intuit their functions.
- Edit: And a bonus bug, the new upgrade that doubles coins but makes blocks sometimes not break when hit? Yeah it just let me achieve 7606 coins collected out of 3610, which was only worth a +Choice and not a +Upgrade.
Also, the choice of control scheme for Mobile is weird, compared to PC. Because the game auto-pauses just by lifting your finger, it's possible to play the game in frame-advance mode, by repeatedly tapping the screen to make coin collection seemingly much easier than intended.
At the same time, it's satisfying to play the game this way, since it lets me effectively multi-task the puck where necessary by tapping the left and right sides of the screen repeatedly to, say, collect two streams of coins at once, or redirect a ball while in the midst of coin collection. If you ever decide to make the mobile control scheme more like PC's, I think you should at least leave the current system as an option.
Despite the bugs, I've had plenty of fun with the game thus far. Just reached 100% unlocks (665728 score total) and my current high score is 79199 from earlier today. By level 10 I had a consistently ~500x multiplier with four max-piercing balls with Hit Streak, maxed Hot Start and Compound Interest, and a bunch of upgrades for easier coin collection and ball repulsion.
Don't need Soft Reset when the combo doesn't reset, and I feel like the combo types based on color or hitting other sides of the screen, even with Soft Reset, just aren't worth it in the long run.
