This game has some really good ideas. The graphics are simple but charming, and the sound effects are really satisfying.
The RNG can be a real pain sometimes. If an upgrade spawns on the opposite side of the screen, there's often no way to reach it before it disappears.
Also, since upgrades spawn over time, I tried to "break" the game. I stopped using the grappling hook and just dodged the starting enemies while waiting for upgrades to spawn, hoping I'd become strong enough to beat the game. After collecting around 20 upgrades, I finally started using the hook. I managed to reach 600 points before dying. This game is tough, I couldn't beat it even with that strategy. xD
