Cool idea and I like the art, but I feel like it would be better if the levels were more open, since I kept getting trapped by the boss

Haha this is a crazy idea, it went from 0 to 100 when I finally figured out how to use the portal thing! I would say the next step would be to create free aiming with the mouse - it kind of feels counter-intuitive to have that necessary, but only dictating the direction you face. Also I love how the gatekeeper looks!

Cool idea and I really like the art!

It's definitely a good start with the upgrades and all the art.

However I felt that while the levels were decent for platforming, their not really meant for bosses....

Nice game but the jumping and movement parameters can be tuned better, it is already hard to jump reliably to get the upgrades so it much harder to win against the boss especially that the gun only shoots horizontally. Other than that, It was fun.

Solid concept, I do love boss rushes. The movement is a bit slow, even with a few upgrades. The arenas don't really feel fit for the bosses. Overall, could use some work and refinement, but It's a good start!

Pretty fun, though I wish after I died I could restart the battle right away instead of having to go through all the powerups. Good stuff though, a nice challenge!

wow is that a stargate? good job man!

Good idea. It's hard to get the power-up text to stay on screen though. Nice work!
