1. hotkeys.
2. bigger bomb radius.
3. drop the price on some of the robot penguin upgrades, or make metal level harders, forcing some grinding.
4. kong achievments.
5. in game achievments (ie. Robot army upgrade- upgrading all 5 penguins to max armor, time trials, beating game in <X number of days, having total of X number of turtle kills, having more than 60k at one point. just to get started
6. increase money grab range.
7. allow a money grab upgrade.
8. balance the money a bit more. level 30 makes sooo much money compared to metal levels
9. fix the ai running into wall issues.
10. make metal levels harder. especially the last 3. i breezed through levels 38-40 without changing a single upgrade.
11. auto-loot money at the end of the level, or add on 2 more seconds after the last penguin is killed
+1 this if you agree with all or any of the points
This game was way too easy past level 5. everything was smooth sailing. i just had to start the level and autofires and money grabbers took care of everything. The only hard part in this game was deciding what to make my ship look like
