Good for playing.

Glitchy, not much to do, endless mode rarely works right.

After waiting 1.5 years with this being on early access android, I was excited to get my hands on it. After grinding for hours upon hours of replaying the same levels, I finally unlocked one of the best planes. “Muscular patchwork bolts.” A day later the game glitched and I cannot select it or use it. It is just check marked on the plane. Support is no use as I have emailed them for help multiple times on their other games with no response ever. Therefore I am not even trying. On top of that all with the game being unplayable, the game is nowhere closed to being finished. There is no game save, half the features say coming soon, daily missions aren’t achievable due to areas of the game not being developed yet, and event planes can’t be unlocked. It’s just a mess but a very fun game with tons of potential. Update; I played level 4 (Hard) while waiting for major bug fixes. The enemies stop appearing and the stage is impossible to pass even after relaunching the game and retrying. I am sure more stages are like this too. At this point, just scrap the game and start over. Unplayable…
