### 2/5 — Not Bad Not Good

*2026-08-28*

It’s an okay game, you know when you’re on an airplane and you didn’t bring any video games and you don’t feel like watching movies, so you resort to airplane games? Yeah it feels like that is the best way I can explain it. Kinda fun for the first 30 minutes then gets kinda eh. There weren’t as many ads as the other reviewers mentioned tho. Its controls are hella easy to understand and the objective is pretty simple. Games not bad, but nor is it good

### 1/5 — Really fun game that is actually locked behind ads

*2026-08-27*

This game is actually great and I would have paid the usual 3-10 dollars on getting rid of ads but that’s not how this game does it they charge you so much money for “ad skip tickets” which is actually the dumbest concept in the world PLEASE DO NOT PLAY

### 2/5 — Recomendação

*2026-08-27*

O jogo em si é bom, mas algumas fases são extremamente difíceis. Mesmo com vídeos propaganda para “ajudar” (e olha que assistir umas 10x) continua complicado, e a aleatoriedade das peças dificulta ainda mais. Precisam de uma atualização!

### 2/5 — Fun but Flawed

*2026-08-26*

Pay to play. Either pay with money or time watching 1+min ads. Takes time to complete a level and can not effectively pause and come back to it like in TD ballon’s and other tower defense games. Needs an undo or redo option to clear mistakes at least once per attempt. 
Lots of good ideas in this game ruined by the punishing cost of time.

### 1/5 — Fun game but really ad heavy and poorly balanced

*2026-08-25*

Beyond the first few levels, this game has a brutal early game - you pretty much are required to watch ads for the extra gold (from the eagle) in order to beat any level. If you’re able to get past this point, the game is actually pretty fun.
Some tips(focused towards f2p):
- Don’t waste gold upgrading common hero’s beyond level 5, your final “Battle Formation” (at least at time of writing) is all 6 epic heroes + frosty & wanderer (the other two legendaries are pay gated)
- Gold is the most important aspect in beating levels, use the bonus gold per level pets (use one of each rarity)
- Try to keep merging to a minimum, merged units deal less damage than two separate units 
- Brick blocks can be placed in mid air by dragging them into another falling block. First place a regular block in the top right corner and then quickly (while the regular block is still above the white line), place a brick block inside it. The final boss wave on regular ladder levels can be cheesed by using 3 brick blocks this way to hit 100m height and unlock the bonus dmg modifier
- Once you beat phase 10 of the mist challenge you can claim 120 pet treats twice a day without needing to play the level
- Watch ads to refresh the daily shop whenever you have free time. Only buy the epic+ heroes using gems, if you use gold you will run out of gold too fast. Only spend gems on buying epic+ heroes and only spend gold on upgrading heroes, don’t waste resources on anything else
- For the mist challenge, the last boss wave is typically the hardest. The final boss attacks super slow though so healing is super important. Try to place as many repairman heroes (unmerged) as possible as if you have enough, you can heal as fast as the boss attacks
- For the mist challenge, watch ads 3 times for bricks and use them to widen the foundation otherwise you will run out of room to place heroes

### 1/5 — Trash game

*2026-08-22*

Waste your time.

### 5/5 — Please keep the updates coming! I really want to see this game grow and improve.

*2026-08-22*

I’m currently at stage 3-5. I’ve been watching plenty of ads to support the game, so could you please add more updates?
I’d love to stack more blocks, but progression feels way too slow. You don’t earn enough money, and that makes the game less enjoyable. Would it be possible to increase the amount of money players earn so they can build larger structures, while lowering the damage to keep things balanced?
You could also add wind that prevents players from stacking blocks in a straight vertical line, which would help stop cheesy strategies.
Another issue is that the block boundaries feel a bit unclear, so it’s hard to place things exactly where I want. I understand that this might be part of the game’s charm, but could you make the blocks fit together a little more smoothly and naturally?

### 1/5 — Ads and crashes

*2026-08-21*

Gets to a point where you can’t advance without ads, then the ads crash the game and lose all progress on the level and waste stamina and time.

### 2/5 — Mario Music- Nintendo licensed

*2026-08-21*

Wait till Nintendo finds out what these guys use for their main menu music 😂😂😂

### 5/5 — Slime up review

*2026-08-20*

Honestly exactly as showed short ads for rewards perfect game for anyone that js wants something for fun and to pass time
