Niko_de_Andjelo (streamer from Tabun):
+1 point for the fun flexing imbalance Chryzzi and the fact that the author understood the unfinished and crookedness of the game, and released a script-killer at 5 minutes.
-1 point for lack of optimization, cut off enemy spawning along with the King Numget spawn at minute 5, boring and poorly implemented other weapons (although the bubble description was fun and on point).
Got through the game at 146%
Proof:

(survived until 15 minutes, despite the fact that the author released a scripted immortal sprite killer at 5:00, which had the only purpose of ending the game before the player realizes that the enemies no longer spawn. I'll note that it's bad for that very reason, and in general, the immortal Reaper itself is a common gimmick in Survivors games that is needed to keep the player from slacking off).
About 45 minutes.
I merely translated the comment from Tabun's user.
